description: The synthesis, characterization and reactivity studies of the NHC-stabilized complex IDipp ⋅ GeH2BH2OTf (1) (IDipp=1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene) are reported. Nucleophilic substitution of the triflate (OTf) group in 1 by phosphine or arsine donors provides access to the cationic group 13/14/15 chains [IDipp ⋅ GeH2BH2ERR1R2]+ (2 E=P; R, R1=H; R2=tBu; 3 E=P; R=H; R1, R2=Ph; 4 a E=P; R, R1, R2=Ph; 4 b E=As; R, R1, R2=Ph). These novel cationic chains were characterized by X-ray crystallography, NMR spectroscopy and mass spectrometry. Moreover, the formation of the parent complexes [IDipp ⋅ GeH2BH2PH3][OTf] (5) and [IDipp ⋅ GeH3][OTf] (6) were achieved by reaction of 1 with PH3. Accompanying DFT computations give insight into the stability of the formed chains with respect to their decomposition.

description: The inclination angle $χ$ between magnetic and rotation axes of pulsars is an important parameter in pulsar physics. The changes in the inclination angle of a pulsar would lead to observable effects, such as changes in the pulse beam width and braking index of the star. In this paper, we perform a short review on the evolution of pulsar's magnetic inclination angle, as well as the latest research progress. Using an alignment rotator model in vacuum, we investigate the magnetic inclination angle change rates for 12 high-braking index pulsars without glitch, whose timing observations are obtained using the Nanshan 25-m Radio Telescope at Xinjiang Astronomical Observatory. For our purpose, three representative pulsars J0157+6212, J1743-3150 and J1857+0526 are chosen and their rotation and inclination angle evolutions are further investigated. In the future, radio and X-ray polarimetric observations will provide more information about the inclination angles of pulsars, which could help us understand the origin of the variations in $χ$ of pulsars and shed light on the range of possibilities of pulsar magnetic field configuration. A continuous study of the pulsar inclination angle will provide an important window into additional physical processes at work in the young and highly magnetized pulsars.

description: Citation text plays a pivotal role in elucidating the connection between scientific documents, demanding an in-depth comprehension of the cited paper. Constructing citations is often time-consuming, requiring researchers to delve into extensive literature and grapple with articulating relevant content. To address this challenge, the field of citation text generation (CTG) has emerged. However, while earlier methods have primarily centered on creating single-sentence citations, practical scenarios frequently necessitate citing multiple papers within a single paragraph. To bridge this gap, we propose a method that leverages Large Language Models (LLMs) to generate multi-citation sentences. Our approach involves a single source paper and a collection of target papers, culminating in a coherent paragraph containing multi-sentence citation text. Furthermore, we introduce a curated dataset named MCG-S2ORC, composed of English-language academic research papers in Computer Science, showcasing multiple citation instances. In our experiments, we evaluate three LLMs LLaMA, Alpaca, and Vicuna to ascertain the most effective model for this endeavor. Additionally, we exhibit enhanced performance by integrating knowledge graphs from target papers into the prompts for generating citation text. This research underscores the potential of harnessing LLMs for citation generation, opening a compelling avenue for exploring the intricate connections between scientific documents.

description: The synthesis and reactivity of the tert-butyl-substituted arsanylborane tBuAsHBH(2) . NMe3 (1) stabilized by a Lewis base (LB) are reported. Compound 1 is obtained by the reaction of in situ generated NatBuAsH with IBH2 . NMe3. By the reaction of 1 with Lewis acids the neutral compounds BBr3 . tBuAsHBH(2) . NMe3 (2) and BH3 . tBuAsHBH(2) . NMe3 (3) as well as coordination products towards Group 6 metal complexes [M(CO)(4)(tBuAsHBH(2) . NMe3)(2)] (M=Cr, Mo, W; 4 a-c) are obtained. Upon reaction with IBH2 . LB (LB=SMe2, NMe3), the cationic oligomeric arsanylboranes [(Me3N . BH(2)tBuAsHBH(2) . NMe3)]I (5) and [H2B(tBuAsHBH(2) . NMe3)(2)]I (6) were isolated. Compound 1 was also used as starting material for the synthesis of the first oligomeric arsanylboranes obtained by thermal oligomerization under different conditions. DFT computations support the experimental observations.

description: The controlled design of functional oligosiloxanes is an important topic in current research. A consecutive Si-O-Si bond cleavage/formation using siloxanes that are substituted with 1,2-diaminobenzene derivatives acting as molecular scissors is presented. The method allows to cut at certain positions of a siloxane scaffold forming a cyclic diaminosilane or -siloxane intermediate and then to introduce new functional siloxy units. The procedure could be extended to a direct one-step cleavage of chlorooligosiloxanes. Both siloxane formation and cleavage proceed with good to excellent yields, high regioselectivity, and great variability of the siloxy units. Control of the selectivity is achieved by the choice of the amino substituent. Insight into the mechanism was provided by low temperature NMR studies and the isolation of a lithiated intermediate.

subject: 540 Chemie

description: Hydrogen and halogen bonds are important anisotropic attractive interactions in the molecular crystalline state. 2,6-dibromophenol (1) was analyzed by single-crystal X-ray diffraction for the first time. The intermolecular interaction pattern was studied by Hirshfeld surface analysis along with 2D fingerprint diagrams. The characteristic interactions that dominate the crystal packing are electrostatic type-II Br...Br interactions, O-H...O hydrogen bonds, and an offset parallel pi-stacking arrangement. Compound 1 was compared with 2,6-difluoro- (2) and 2-bromo-6-chlorophenol (3) in terms of their interplay between hydrogen and halogen bonding. Whereas the O-H...O hydrogen bond is more pronounced in the lighter homologues, the halogen...halogen interaction becomes a particularly important directional, attractive interaction in the crystal structure of 2,6-dibromophenol.

Type species, Procystiphora coloradensis Felt, 1915 (orig. des.).
With the description of the new species, this Holarctic genus consists of five plant-feeding species including the new species. Three, including the new species, are distributed in the Palaearctic and two in the Nearctic. Sato et al. (2009) redescribed Procystiphora and gave a detailed generic diagnosis. In the present paper, some parts of the generic diagnosis are broadened as follows to contain all known Procystiphora species: female eighth tergite incised or concave deeply only posteriorly or both posteriorly and anteriorly; male hypoproct with lobes pointed apically or rounded apically; empodium longer than or as long as tarsal claw. The differences between Procystiphora and other allied genera may be found in Gagné (1975) and Skuhravá (1997).

description: The 2-pyrone moiety can be found in a large number of natural products with a wide range of biological activities, including antibiotic, antifungal, cytotoxic, neurotoxic, phytotoxic, anti-inflammatory and cardiotonic effects. With its heterocyclic structure encompassing the chemical nature of conjugated dienes, lactones, Michael acceptors and arenes, it can undergo a great variety of transformations such as cycloadditions, ring-opening reactions, cross-couplings and lactamizations. Thus, 2-pyrones represent valuable synthetic precursors and worthwhile targets in organic, polymer, and medical chemistry. Owing to its exquisite chemical and physical properties, the synthesis and further transformations of 2-pyrones have attracted considerable attention over the past decade, showcasing transition metal and metal free strategies and using readily available starting materials, notably those stemming from renewable resources.

description: As a result of continuous instrumental progress, capillary electrophoresis has become an established separation technique. However, the choice of the suitable capillary inner diameter is sometimes difficult due to different instrumental requirements concerning injection, separation, or detection. To overcome this problem, we assembled two capillaries with different inner diameters, meaning that the inner diameter of the capillary at the injection side was different from that at the detection side. Since this was a rather uncommon approach, we focused on the associated effects in this proof-of-concept study. For the experiments, a non-aqueous model system was used, consisting of an acetonitrile-based background electrolyte and the two ferrocene derivates, ferrocenemethanol and decamethylferrocene. Using capillary flow injection analysis hyphenated to capacitively coupled contactless conductivity detection, it could be shown that fragmented capillaries of the same inner diameter had slightly lower volume flow rates than non-fragmented capillaries. With non-aqueous capillary electrophoresis hyphenated to UV detection, it was found that the coupling of capillaries with different inner diameter had a much stronger effect on the capillary electrophoresis flow than combinations with the same inner diameter. Additionally, if the inner diameter of the second capillary was larger than the inner diameter of the first capillary, a higher theoretical plate number and an increased sensitivity were found. Furthermore, it was found that there was no significant peak tailing introduced by the coupling.

description: The decision-making process for an investor crucially hinges on selecting a portfolio that offers maximum benefits, given the associated risk levels of investment stocks. This research aims to evaluate optimal management of agricultural portfolio to enhance profit margins while mitigating risks. Ten (10) agricultural stocks were analyzed as variables using a linear programming model, with the utilization of Tora package based on Big M and Two-Phase methods to derive an optimal solution. Findings indicated that out of the 10 stocks considered, only Rice and Cocoa should be selected for investment to yield maximum returns. Sensitivity analysis revealed that a decrease or increase in the available resources would subsequently lead to a decrease or increase in the optimal profit. This research provides insights into optimal management of portfolio, and offers a practical framework for investors in the agricultural sector.

description: The generation of diphosphorus molecules P-2 under mild conditions in solution is a useful strategy to generate diphosphines via [4+2] cycloadditions. We recently described the release of P-2 units from the nickel butterfly complex [{(IMes)Ni(CO)}(2)(mu(2),eta(2):eta(2)-P-2)] (IMes=1,3-bis(2,4,6-trimethylphenyl)imidazolin-2-ylidene) upon addition of CO gas. Herein, we developed an alternative protocol for the same process using heterocumulenes. In addition to formation of P-4 (the dimerisation product of P-2), the reactions afford nickel complexes of novel pincer-type ligands. Aryl isothiocyanates undergo a trimerisation within the coordination sphere of nickel and afford square planar nickel complexes with S-C-S pincer-ligand frameworks. Carbon disulfide coordinates to the [(IMes)Ni]-fragment in an eta(2)-fashion, affording a dinuclear complex. Similar products are formed when the N-heterocyclic carbene nickel(0) complex [(IMes)Ni(vtms)(2)] is used as a precursor (vtms=vinyltrimethylsilane).
