Anionic Access to Silylated and Germylated Binuclear Heterocycles
Authors: Boddaert Thomas , François Cyril , Mistico Laetitia , Querolle Olivier , Meerpoel Lieven , Angibaud Patrick , Durandetti Muriel , Maddaluno Jacques
Published: July 2014

A simple access to silylated and germylated binuclear heterocycles, based on an original anionic rearrangement, is described. A set of electron‐rich and electron‐poor silylated aromatic and heteroaromatic substrates were tested to understand the mechanism and the factors controlling this rearrangement, in particular its regioselectivity. This parameter was shown to follow the rules proposed before from a few examples. Then, the effect of the substituents borne by the silicon itself, in particular the selectivity of the ligand transfer, was studied. Additionally, this chemistry was extended to germylated substrates. A hypervalent germanium species, comparable to the putative intermediate proposed with silicon, seems to be involved. However, a pathway implicating the elimination of LiCH2Cl was observed for the first time with this element, leading to unexpected products of the benzo‐oxa (or benzo‐aza) germol‐type.

Metal‐Organic Gels Based on Carboxyl‐Functionalized Benzimidazole and Their Stimuli Responsivenesses
Authors: Yao Hong , You Xingmei , Lin Qi , Wu Hongping , Wei Taibao , Zhang Youming
Published: July 2014

Three multi‐responsiveness supramolecular metal‐organic gels (MOGs) have been prepared upon Ba(OAc)2, CdSO4·8H2O and Pb(NO3)2 with a simple ligand (G17) based on a carboxyl‐functionalized benzimidazole derivative in alcoholic‐water solutions. The MOGs display the formation of well‐developed nanofibrillar networks composed of intertwined fibers which provide stability to gels structures through coordination, hydrogen bonding and π‐ π interactions characterized by using field emission scanning electron microscopy (FESEM), the fourier transform infrared (FT‐IR) spectroscopy and powder X‐ray diffraction (XRD) techniques. MOG‐1 shows good stimuli responsiveness toward the changes in K2CrO4, both MOG‐2 and MOG‐3 do good job toward the changes in Na2S. Moreover, because these MOGs were formed easily by gelator with some heavy metal ion, such as Cd(II) and Pb(II), it might provide the basis for heavy metal ion capture and removal.
Adsorption Mechanism of Acetylene Hydrogenation
Authors: Xie Xuejia , Song Xiuli , Dong Wenyan , Liang Zhenhai , Fan Caimei , Han Peide
Published: July 2014

First‐principles calculations are carried out to examine the adsorption of acetylene over the Pd (111) surface. A hydrogen adsorption system is initially investigated to confirm the reliability of the selected calculation method. Adsorption energies, Mulliken‐populations, overlap populations, charge density, and projected density of states (PDOS) are then calculated in the optimised acetylene adsorption system. Results show that C2H2 molecule tends to adsorb through the threefold parallel‐bridge configuration that is computed to be the most stable. In this structure, the distance of the CH bond is calculated to be 1.09 Å, and the C‐C‐H bond angle is 128°. The distance of the CC bond in acetylene is 1.36 Å, increasing from 1.21 Å in the gas phase. Moreover, the CC bond overlap population decreases from 1.98 to 1.38, revealing that the carbon configuration in C2H2 rehybridises from sp to sp2 and beyond. The obtained results are compared with available experimental studies on acetylene hydrogenation on single‐metal surfaces. The PDOS study indicates that a carbonaceous layer may generate on the metal surface during acetylene adsorption. The carbonaceous layer can affect the adsorption and reaction of acetylene, thereby inactivating the metal surface. Our experiments also show that Pd exhibits high catalytic activity.
Ordered Ultrathin Films of Perylene Anions and Layered Double Hydroxide Using Exfoliation‐coassembly Method
Authors: Zhang Yingkui , Song Ming , Yun Rongping , Meng Qingyun , Yan Dongpeng
Published: July 2014

Recently, the fabrication of ordered luminescent ultrathin film (UTF) materials based on layered double hydroxides (LDHs) has received much attention. However, how to obtain these UTFs assembled by small anions and LDHs nanosheets is still a challenge. Herein, perylene 3,4,9,10‐tetracarboxylate (PTCB) was firstly chosen as the anion with the aim to obtain PTCB/LDH UTFs, which cannot be formed based on typical layer‐by‐layer (LBL) method. Then, the polymer anions (such as poly 4‐styrene sulfonate (PSS) and poly vinyl sulfonate (PVS)) were further chosen as the co‐assembled units with PTCB, which can act as carriers to assemble with LDH nanosheets. The as‐obtained PTCB@PSS/LDH and PTCB@PVS/LDH UTFs present long range ordered structures confirmed by powder X‐ray diffraction (XRD), scanning electron microscopy (SEM) and atomic force microscopy (AFM). Moreover, these two UTF systems show polarized luminescence with the emissive anisotropy of ca. 0.62 and 0.73. Therefore, this work presents an exfoliation‐coassembly way to develop LDH‐based ordered luminescent films, which may benefit their future optical display applications.
Advanced conventional chondrosarcomas: Time to revisit treatments and clinical research for what is not an indolent disease
Authors: Italiano Antoine
Published: July 2014

Medical and surgical oncologists involved in the management of patients with sarcoma know well that the management of those with recurrent chondrosarcoma is quite challenging. In light of the currently available data, anthracycline‐based chemotherapy and radiotherapy represent reasonable options for chondrosarcoma patients not eligible to a clinical trial with good performance status and who have unresectable metastatic or locally advanced disease, respectively.
