Preparation of PANI Modified ZnO Composites via Different Methods: Structural, Morphological and Photocatalytic Properties
Authors: Turkten Nazli , Karatas Yunus , Bekbolet Miray
Published: April 2021

Polyaniline modified zinc oxide (PANI-ZnO) photocatalyst composites were synthesized by focusing on dissolution disadvantage of ZnO. In-Situ chemical oxidation polymerization method was performed under neutral conditions (PANI-ES) whereas in hybridization method physical blending was applied using emeraldine base of polyaniline (PANI-EB). PANI-ZnO composites were prepared in various ratios of aniline (ANI) to ZnO as 1%, 3%, 6% and 9%. The alterations on the structural and morphological properties of PANI-ZnO composites were compared by Fourier Transform Infrared (FT-IR), Raman Spectroscopy, X-ray Diffraction (XRD) and Scanning Electron Microscopy-Energy Dispersive X-ray Analysis Unit (SEM-EDAX) techniques. FT-IR and Raman spectroscopy confirmed the presence of PANI in all composites. SEM images revealed the morphological differences of PANI-ZnO composites based on PANI presence and preparation methods. Photocatalytic performances of PANI-ZnO specimens were investigated by following the degradation of methylene blue (MB) in aqueous medium under UVA irradiation. The effects of catalyst dose and initial dye concentration were also studied. MB degradation was followed by both decolorization extents and removal of aromatic fractions. PANI-ZnO composites expressed enhanced photocatalytic performance (~95% for both methods) as compared to sole ZnO (~87%). The hybridization method was found to be more efficient than the In-Situ chemical oxidation polymerization method emphasizing the significance of the neutral medium.
INFLUENCE OF MICROSTRUCTURE OF HYDRATE PHASES OF CEMENT STONE ON CONCRETE DURABILITY
Authors: Trofimov B. , Shuldyakov K. , Mahmudov A.
Published: April 2021

One of the main problems in modern concrete science is the low durability of reinforced concrete structures and constructions, especially those located in harsh climatic conditions and saturated with marine or mineralized water. Existing standards guide designers and builders to increase the density of concrete with increasing degree of aggressive impact, as well as through cyclical freezing of concrete structures, which taken as the main indicator of durability, air entrainment is mandatory. The problem is not only the provision of high frost resistance of concrete, but also finding a method of controlling it, which, as a rule, takes quite a long time. The destruction of concrete during cyclical freezing occurs not only due to the formation of ice in the pores of concrete, but also as a result of temperature stresses in concrete with ice, as well as the washing out of portlandite and aging of the cement gel – the main structural element of hardened cement paste. This means that the durability of the concrete can be ensured by maintaining the finely dispersed structure of the hardened cement paste, preventing crystallization of the gel from external influences or increasing its basicity. It is shown that only water reduction and pozzolanization, which provides residual portlandite content in Portland cement concrete stone 2–5 % by weight ensure the achievement of increased durability of concrete, reinforced concrete structures and constructions. A method is proposed to assess the stability of hydrate phases as well as the relationship between the durability and frost resistance of concrete.
Aos Clichês: o cinema na cultura midiática e de consumo
Authors: Bezerra Julio
Published: April 2021

Vivemos hoje em um arranjo social em que os meios de comunicação e a cultura de consumo não podem mais ser pensados em separado, em que as imagens midiáticas são consumidas e usadas de forma crescente como fontes para construir e expressar certas identidades. O cinema nos ajuda a ampliar os contornos deste cenário. Filmar hoje é mergulhar num turbilhão de clichês, de imagens prontas, num fluxo midiático ininterrupto. O objetivo deste artigo é pensar esta temática através de análises de três obras: “Apenas o fim” (2008), de Matheus Souza, “Pacific” (2009), de Marcelo Pedroso, e a série “Eastbound & Down” (2009-2011), de David Gordon Green e Jody Hill.

Moda e Publicidade no Brasil: uma relação histórica permeada por hibridismos
Authors: Maia Midierson
Published: April 2021

Com base em uma análise dos históricos da moda e da publicidade no Brasil, o artigo visa entender o percurso de formação de ambas como parte de um todo, no qual, por meio de hibridismos oriundos dos contatos entre diferentes culturas, incide o fenômeno cultural da glocalização. Para tanto, os trabalhos desenvolvidos pelos pesquisadores Garcia Canclini, Roland Robertson, Garcia Neira e Eneus Trindade servirão como base para o entendimento das relações estabelecidas entre a moda e a publicidade na qualidade de manifestações híbridas, que contribuiram e continuam contribuindo na formação da identidade e cultura nacional. A aplicação prática das teorias se deu por meio da análise de peças publicitárias veiculadas desde décadas remotas até as décadas de 90 e início do século XXI. O resultado do trabalho mostrou que tanto a moda, quanto a publicidade, ao unirem entre si e ao se glocalizarem na relação com outros contextos, agregam sentido à cultura, em especial à cultura do consumo.
Da Alegoria Continental às Jornadas Interiores: o road movie latino-americano contemporâneo
Authors: Prysthon Ângela
Published: April 2021

Assim como a literatura de viagem está geralmente associada à expansão do colonialismo europeu, o road movie é normalmente definido como um gênero cinematográfico norte-americano por excelência - aquele ao qual pertencem Easy Rider, Thelma and Louise, Lost Highway, só para mencionar alguns dos mais emblemáticos. O propósito deste artigo é comparar algumas apropriações deste gênero na América Latina. Algumas que exacerbam o caráter alegórico das viagens pelo continente (como El Viaje (1992) de Pino Solanas, Guantanamera (1996) de Tomás Gutierrez Alea e Diários de Motocicleta (2003) de Walter Salles), outras que buscam através de um maior intimismo revelar as singularidades dos seus personagens viajantes, como Terra Estrangeira (1993) de Walter Salles Jr. e alguns filmes dos anos 2000 que optam por esse segundo registro: Y tu mamá también (2001) de Alfonso Cuarón e Historias Mínimas (2002) de Carlos Sorín.
Need to change the design of investigative actions aimed at obtaining information transmitted by means of communication
Authors: Stel'mah Vladimir
Published: April 2021

Abstract: Relevance of the research topic. The obvious trend of social activity was the digitalization of almost all aspects of people’s lives, which led to a sharp increase in information transmitted in digital (electronic) form. The Criminal Procedure Law provides for investigative actions aimed at obtaining this information for subsequent use in criminal evidence. However, some changes to the law are not quite systemic, are not supported by theoretical studies, which complicates law enforcement practice, forms the prerequisites for violating the uniformity of application of the law, and infringement of the rights of participants in criminal procedure. Problem setting. The constant improvement of the means of communication objectively leads to an expansion of their scope. In response, the legislator designs investigative actions that allow obtaining information transmitted by means of communication. However, some legislative decisions could not be considered optimal. Thus, having fixed in Art. 185 of the Code of Criminal Procedure of the Russian Federation the possibility of obtaining information transmitted by e-mail, the legislator did not take into account that this norm applies only to postal operators. In addition, since 2018, telecommunication operators have been required to record and store the content of all communication sessions served by them. However, these provisions are not taken into account in the criminal procedure law, which establishes another procedure for obtaining information. Research objectives and methods. The purpose of the study is to develop proposals for improving the normative design of investigative actions aimed at obtaining information transmitted by means of communication. The tasks of the study are to analyze the provisions of the Criminal Procedure Law and the legislation on communication, to identify conflicts between them. The methodological basis of the study was the dialectical-materialistic method, as well as the general scientific methods of scientific knowledge: analysis and synthesis, induction and deduction, formal-logical, systemic. Results and key findings. To eliminate the resulting collision, it is necessary to design a universal investigative action that allows you to obtain information transmitted by telecommunication means, both the content of negotiations and the billing parameters of the connection.

The right to life in the system of constitutional rights and freedoms of individual and citizen
Authors: Amel'chakov Oleg
Published: April 2021

The right to life is traditionally recognized as a natural and inalienable right of any person and citizen. It is intrinsically connected with realization of other rights and liberties.

The aim of the article is to clarify the concept and the essential nature of the constitutional right to life, to define its place in the system of fundamental human and civil rights and liberties. The article analyses constitutional rights, reveals the difference from the other human and civil rights and liberties and analysis other approaches of constitutional rights theoretic to the definition of the notion «right to life» as a constitutional right. The research gives the monitoring of the main statutory documents that defines the legal «understructure» of fixation and content of the notion «right to life» and the review of the foreign constitutional statutory documents that are devoted to the different aspects of law.

Based on the results of the research a conclusion was made that the right to life takes a special place in the system of the constitutional rights and freedoms. The right to life is the inherent human right and this is admitted on the international level. Being fundamental in nature, it is based on the constitutional norms and principles, which set up uniformity of appliance and mechanisms for ensuring and protecting the right to life.
Problems of implementation of constitutional rights and freedoms of man and citizen in the context of COVID-19
Authors: Astafichev Pavel
Published: April 2021

The article is devoted to the study of a range of problems concerning the implementation of constitutional human rights and freedoms in the context of the threat of the spread of a new coronavirus infection. The author states that from the point of view of the implementation of the institution of constitutional rights and freedoms of man and citizen, the legal regulation pattern was likely to be the strengthening of guarantee of the constitutional right to the protection of life and health, in part, to the detriment of other constitutional rights and freedoms, first of all – the right to freedom of movement, personal privacy, work, freedom of individual enterprise, right to education, access to arts, culture and cultural values and use of cultural establishments. In case of COVID-19, preference was forced upon de facto federalism, which implies a reasonable decentralization of the subjects of jurisdiction and powers, vertical sharing of powers to guarantee the constitutional principle of separation of powers. The article proves that the executive power has the right to plan and organize sanitary and anti-epidemiological, preventive and even restrictive measures, but it cannot limit the constitutional rights and freedoms of citizens bypassing the will of the representation of the people in a democratic society. In extremis, when circumstances require an immediate solution, it is possible only for a very short time, used by a representative body to fully discuss and make a proper decision.

Published: April 2021

ZnO nanowires were grown by mist chemical vapor deposition at a growth temperature of approximately 900 °C (tube furnace temperature) on a c-plane sapphire substrate sputtered with a thin Au layer with a designed thickness of 3 nm. ZnO nanowires of various lengths were grown, and their optical properties were investigated by room-temperature photoluminescence (RT-PL) measurements under high excitation conditions. The RT-PL spectra having sharp peaks may be capable of lasing actions. The result shows that this fabrication technique is useful for obtaining optical microcavities based on ZnO nanowires.

Authors: Gu Yu , Zhang Xiang , Yan Huan , Liu Zhi , Ren Fuji
Published: April 2021

High-quality sleep is essential to our daily lives, and real-time monitoring of vital signs during sleep is beneficial. Current sleep monitoring solutions are mostly based on wearable sensors or cameras, the former is worse for sleep quality, the latter is worse for privacy, dissimilar to such methods, we implement our sleep monitoring system based on COTS WiFi devices. There are two challenges need to be overcome in the system implementation process: First, the torso deformation caused by breathing/heartbeat is weak, how to effectively capture this deformation? Second, movements such as turning over will affect the accuracy of vital signs monitoring, how to quickly distinguish such movements? For the former, we propose a motion detection capability enhancement method based on Rice-K theory and Fresnel theory. For the latter, we propose a sleep motion positioning algorithm based on regularity detection. The experimental results indicated the performance of our method.
DeepLPC: A Deep Learning Approach to Augmented Kalman Filter-Based Single-Channel Speech Enhancement
Authors: Roy Sujan Kumar , Nicolson Aaron , Paliwal Kuldip K.
Published: April 2021

Current deep learning approaches to linear prediction coefficient (LPC) estimation for the augmented Kalman filter (AKF) produce bias estimates, due to the use of a whitening filter. This severely degrades the perceived quality and intelligibility of enhanced speech produced by the AKF. In this paper, we propose a deep learning framework that produces clean speech and noise LPC estimates with significantly less bias than previous methods, by avoiding the use of a whitening filter. The proposed framework, called DeepLPC, jointly estimates the clean speech and noise LPC power spectra. The estimated clean speech and noise LPC power spectra are passed through the inverse Fourier transform to form autocorrelation matrices, which are then solved by the Levinson-Durbin recursion to form the LPCs and prediction error variances of the speech and noise for the AKF. The performance of DeepLPC is evaluated on the NOIZEUS and DEMAND Voice Bank datasets using subjective AB listening tests, as well as seven different objective measures (CSIG, CBAK, COVL, PESQ, STOI, SegSNR, and SI-SDR). DeepLPC is compared to six existing deep learning-based methods. Compared to other deep learning approaches to clean speech LPC estimation, DeepLPC produces a lower spectral distortion (SD) level than existing methods, confirming that it exhibits less bias. DeepLPC also produced higher objective scores than any of the competing methods (with an improvement of 0.11 for CSIG, 0.15 for CBAK, 0.14 for COVL, 0.13 for PESQ, 2.66\% for STOI, 1.11 dB for SegSNR, and 1.05 dB for SI-SDR, over the next best method). The enhanced speech produced by DeepLPC was also the most preferred by listeners. By producing less biased clean speech and noise LPC estimates, DeepLPC enables the AKF to produce enhanced speech at a higher quality and intelligibility.

Legionella pneumophila — The causative agent of Legionnaires’ disease
Authors: Tan Loh Teng Hern , Tee Wei Yu , Khan Tahir Mehmood , Ming Long Chiau , Letchumanan Vengadesh
Published: April 2021

Over the years, Legionella pneumophila has increasingly become a public health threat that causes sporadic and epidemic community-acquired and nosocomial-acquired pneumonia. Thus, this review aims to discuss the current knowledge of L. pneumophila, focusing on the global epidemiology, clinical features, diagnosis and treatment of Legionnaires’ disease (LD). Legionella bacteria are Gram-negative rod-shaped bacteria that are ubiquitous in aquatic environments. L. pneumophila was first discovered in 1976 and recognized as the causative agent of LD. L. pneumophila is a facultative intracellular pathogen that infects and replicates within eukaryotic host cells such as macrophages and protozoan. Diagnosis of LD remains a significant challenge as the clinical manifestation of LD is hardly distinguishable from pneumonia caused by other respiratory pathogens. Therefore, early testing and appropriate treatment are keys to alleviating the rising morbidity and mortality caused by LD.

Дотримання вимог платформи IoT за допомогою хмарних рішень.
Authors: Старовойтенко O.
Published: April 2021

Інтернет речей (IoT) надає широкий спектр програм, що забезпечують підвищену обізнаність та контроль за фізичним середовищем. Поточні системи, як правило, локально сприймають і опрацьовують фізичні явища, а потім переносяться на хмарну інфраструктуру pub / sub (публікації / підписки) для розподілу даних датчиків та контролю серед кінцевих користувачів та зовнішніх служб. Незважаючи на популярність рішень pub / sub досі незрозуміло, які функції проміжне програмне забезпечення повинно мати, щоб успішно відповідати конкретним вимогам домену IoT. Питання як велика кількість підключених пристроїв, які лише епізодично надсилають невеликі повідомлення датчиків, впливають на пропускну здатність. У цій роботі ми розглядаємо дані обмеження, аналізуючи основні вимоги платформ IoT та оцінюючи, які з цих функцій підтримуються відомими opensource (відкритими рішеннями)pub / sub. Далі ми проведемо оцінку продуктивності в загальнодоступній хмарі, використовуючи чотири популярні реалізації pub / sub: RabbitMQ (AMQP), Mosquitto (MQTT), Ejabberd (XMPP) та ZeroMQ. Ми дослідимо максимальну стійку пропускну здатність та затримку в справжніх умовах навантаження, використовуючи дані від реальних датчиків. Хоча основні функції подібні, аналізовані системи pub / sub відрізняються своїми можливостями фільтрації, семантичними гарантіями та кодуванням. Наша оцінка показує, що ці відмінності можуть мати помітний вплив на пропускну здатність та затримку хмарних платформ IoT.

Published: April 2021

Nothing vast comes into a mortal’s life without a curse. Identifying the pathways of pesticide impact can be multifaceted as well as complex, as humankind faces the magnificent challenge of food systems reconfiguration toward providing and delivering healthy foods that individuals can access while protecting planetary health. Ideally, chemical pesticides used inappropriately in agricultural activities has shaped serious health as well as environmental problems in the global south. The United Nations Environment Program (UNEP) as well as World Health Organization (WHO) approximate that the rates of pesticide poisoning occur 2-3 times per minute, having roughly 20,000 employees dying yearly from exposure, mostly in emerging countries. From an environmental point of view, “chemically-polluted runoff” comes through fields that pollute both ground as well as surface waters, destroying freshwater ecosystems, damaged fisheries, as well as creating growing and sustainable "dead zones" in the coastal areas near the river’s mouths of the drain agricultural areas. The environmental as well as health hazards resulting from pesticides could remain comparatively avoided through education as the first step towards achieving the SDGs as well as creating sustainable incentives toward curbing the overuse trend.  Other important challenges need to be resolved, for example social inclusion; poverty reduction; education, increased equity as well as health care; sustainable energy; conservation of biodiversity; water security; and changing climate adaptation as well as mitigation. These challenges are interlinked as well as embodied in 2030 Agenda for Sustainable Development, which all UN member states have accepted since 2015 as well as built round the 17 Sustainable Development Goals (SDGs). Therefore, managing the rapid accelerators considerately will need negotiation as well as collaboration from a wide range of civil society sector, private as well as public actors. The time has come toward putting the challenge of sociotechnical innovation as well as massive human ingenuity toward usage to safeguard the next generations as well as the planet future. While, the world is not on the pathway toward realizing its global goals come 2030. Prior to the outbreak of COVID-19, uneven progress had been witnessed, as well as more focused considerations was required in many areas. The sudden onset of the pandemic abruptly hampered the SDGs implementation and, in other cases, twisted decades of progress backwards.

On one hand, the diversity of activities and on the other hand, the conflicts between beneficiaries necessitate the efficient management and supervision of coastal areas. Accordingly, monitoring and evaluation of such areas can be considered as a critical factor in the national development and directorship of the sources. With regard to this fact, remote sourcing technologies with use of analytical operations of geographic information systems (GIS), will be remarkably advantageous. Iran’s south-eastern Makran coasts are geopolitically and economically, of importance due to their strategic characteristics but have been neglected and their development and transit infrastructure are significantly beyond the international standards. Therefore, in this paper, with regard to the importance of developing Makran coasts, a Multi-Criterion Decision Analysis (MCDA) method was applied to identify and prioritize the intended criteria and parameters of zoning, in order to establish new maritime zones. The major scope of this study is to employ the satellite data, remote sensing methods, and regional statistics obtained from Jask synoptic station and investigate the region’s status in terms of topography, rainfall rate and temperature changes to reach to a comprehensive monitoring and zoning of the coastal line and to provide a pervasive local data base via use of GIS and MCDA, which will be implemented to construct the coastal regions.In this article, while explaining the steps of coastal monitoring, its main objectives are also explained and the necessary procedures for doing so are presented. Then, the general steps of marine climate identification and study of marine parameters are stated and the final achievements of the coastal monitoring process are determined. In the following, considering that this article focuses on the monitoring of Makran beaches, the method of work in the mentioned region will be described and its specific differences and complexities will be discussed in detail. Also, the impact of such projects on future research results will be discussed.

Almost Intersecting Families
Authors: Frankl Peter , Kupavskii Andrey
Published: April 2021

Let $n > k > 1$ be integers, $[n] = \{1, \ldots, n\}$. Let $\mathcal F$ be a family of $k$-subsets of $[n]$. The family $\mathcal F$ is called intersecting if $F \cap F' \neq \varnothing$ for all $F, F' \in \mathcal F$. It is called almost intersecting if it is not intersecting but to every $F \in \mathcal F$ there is at most one $F'\in \mathcal F$ satisfying $F \cap F' = \varnothing$. Gerbner et al. proved that if $n \geq 2k + 2$ then $|\mathcal F| \leqslant {n - 1\choose k - 1}$ holds for almost  intersecting families. Our main result implies the considerably stronger and best possible bound $|\mathcal F| \leqslant {n - 1\choose k - 1} - {n - k - 1\choose k - 1} + 2$ for $n > (2 + o(1))k$, $k\ge 3$.
Analyzing the Manufacturing Supply Chain Performance for Urgent Item During COVID-19 Outbreak
Authors: Arishi Ali , Krishnan Krishna K , Maru Vatsal
Published: April 2021

As COVID-19 pandemic spreads in different regions with varying intensity, supply chains (SC) need to utilize an effective mechanism to adjust spike in both supply and demand of resources, and need techniques to detect unexpected behavior in SC at an early stage. During COVID-19 pandemic, the demand of medical supplies and essential products increases unexpectedly while the availability of recourses and raw materials decreases significantly. As such, the questions of SC and society survivability were raised. Responding to this urgent demand quickly and predicting how it will vary as the pandemic progresses is a key modeling question. In this research, we take the initiative in addressing the impact of COVID-19 disruption on manufacturing SC performance overwhelmed by the unprecedented demands of urgent items by developing a digital twin model for the manufacturing SC. In this model, we combine system dynamic simulation and artificial intelligence to dynamically monitor SC performance and predict SC reaction patterns. The simulation modeling is used to study the disruption propagation in the manufacturing SC and the efficiency of the recovery policy. Then based on this model, we develop artificial neural network models to learn from disruptions and make an online prediction of potential risks. The developed digital twin model is aimed to operate in real-time for early identification of disruptions and the respective SC reaction patterns to increase SC visibility and resilience.
Workplace Assigned Mobile Communication Devices and Employee Stress
Authors: Desai Anoop A , Ball Michael
Published: April 2021

A literature review of the important role played by stress in workplace performance, the correlation between workplace assigned mobile communication devices and stress as well as measures that can be taken to alleviate such stress is presented in this paper. Workplace stress can cause problems ranging from mild anxiety to serious problems which could cause death. Stress can also have an adverse effect on the productivity and morale of employees. The modern workplace is rife with a large variety of stressors. With the rapid advance in communications technology, mobile communication devices are new possible stressors which have become widely prevalent over the past few years. These devices allow employees to be in constant communication with workplace activities. They are invaluable tools for employees who travel frequently and who are required to be on call. This paper seeks to present a review of current literature that investigates the possible correlation between workplace stress and mobile communication devices. Managers that require employees to monitor their communication device after work hours and while on vacation could be placing undue stress on their employees’ well-being. Some employees feel that they will miss out on something or get into trouble if they are not in constant communication. A separation between work and personal life must be present to reduce stress among employees and managers. Such a separation is vital to the health and well being of all concerned.
The role played by workplace assigned mobile communication devices has been studied in this paper. This is a timely addition to the literature in this area in light of the increasingly ‘mobile’ nature of the modern workplace.
A Mathematical Model for In-Person Office Assignment During COVID-19
Authors: Santos Daryl
Published: April 2021

The global pandemic that is COVID-19 has altered our world as we know it. Educational systems have been seriously affected, businesses – whether “essential” or not – have been severely stressed, how people socialize has, perhaps forever, been changed, and telecommuting is the new norm. The purpose of this paper is to discuss a situation wherein a company was having difficulty in scheduling their in-person office staffing in a move to allow rotational schedules for their employees to decongest their office when an entirely telecommuting operation was not possible. Due to the different types of employees, their various work-related constraints, and the need to minimize the number of bodies in the office while addressing minimum coverage necessary to perform the company’s daily activities, a quick solution to their scheduling/assignment needs was not obvious or trivially obtained. As such, mathematical models, specifically, integer programming assignment models, were developed and ultimately solved using the Python/Gurobi solver to address their scheduling needs. This paper will describe the constraints faced by the company and the models developed to solve their tricky assignment problem.

Consequências jurídicas do descumprimento da função socioambiental da propriedade rural no Brasil
Authors: Rosa Vanessa De Castro , De Almeida Mateus Bachiega
Published: April 2021

A função social da propriedade, garantida constitucionalmente, impõe o dever de usar a propriedade rural de forma racional e ecológica. O presente artigo analisa o conceito de função socioambiental da propriedade rural do Brasil, além de verificar a possibilidade de realizar a desapropriação para fins de reforma agrária permitindo a alteração da injusta estrutura fundiária do país. Para tal análise, foi realizada uma comparação entre o antigo pensamento individualista da propriedade e o modelo novo vinculado à função social. Partindo do paradigma teórico e axiológico da sociabilidade, foram analisados os artigos da Constituição da República que determinam os requisitos para que essa função seja efetivamente cumprida, a fim de analisar as diferentes interpretações, principalmente em relação à expressão “propriedade produtiva” do artigo 185 e, por fim, quais são as consequências do descumprimento da função social. O trabalho foi realizado por pesquisa bibliográfica e documental, com análise de julgados atinentes à função socioambiental da propriedade.

After completing the thio-substitution with Lawesson’s reagent, ethanol was found to be effective in the decomposition of the inherent stoichiometric six-membered-ring byproduct from the Lawesson’s reagent to a highly polarized diethyl thiophosphonate. The treatment significantly simplified the following chromatography purification of the desired thioamide in a small scale preparation. As scaling up the preparation of two pincer-type thioamides, we have successfully developed a convenient process with ethylene glycol to replace ethanol during the workup, including a traditional phase separation, extraction, and recrystallization. The newly developed chromatography-free procedure did not generate P-containing aqueous waste, and only organic effluents were discharged. It is believed that the optimized procedure offers the great opportunity of applying the Lawesson’s reagent for various thio-substitution reactions on a large scale.
