02-Jul-2015 | Xun Zhang, Jing Li, Hua Tian, Yian Shi, Chemistry - A European Journal, 2015
Abstract The dimeric cinchona alkaloid (DHQD)2PHAL is used to catalyze an effective asymmetric bromohydroxylation of unfunctionalized olefins with H2O as nucleophile an N‐bromobenzamide as a bromine source. A variety of optically active bromohydrins are formed with up to 88 % ee. PHAL’s ...
02-Jul-2015 | Hu Huang, Hongjie Pan, Yudong Cai, Mao Liu, Hua Tian, Yian Shi, ChemInform, 2015
Abstract Optically active 5‐bromo‐1,3‐oxazinan‐2‐ones are synthesized with excellent enantioselectivities and good yields by using DBDMH as the bromine source.
02-Jul-2015 | Kun Lu; Qingguo Huang; Peng Wang; Liang Mao, Environmental Science & Technology, 2015
The environmental implications of graphene have received much attention, however, little is known about how graphene affects or may be affected by the enzymatic reactions that are critically involved in natural organic matter transformation processes. We conducted experiments to examine the role ...
02-Jul-2015 | Chintada Nageswara Rao; Faiz Ahmed Khan, Synthesis, 2015
SynthesisDOI: 10.1055/s-0034-1378843 A selective debromination of tetracyclic dibrominated bis-γ-lactones in the presence of triethylamine and mesyl chloride is reported. Both mesyl chloride and triethylamine are essential for the debromination process. The reduction is proposed to proceed ...
27-Jun-2015 | Atif Mahammed, Zeev Gross, Angewandte Chemie International Edition, 2015
Abstract Photochemical oxidation of halide anions by visible light has been suggested for solar energy conversion processes. Post‐transition metallocorroles are now disclosed as very efficient catalysts for the photoinduced transformation of bromide to bromine. The advantages of these ...
26-Jun-2015 | Yan‐Zhen Zheng, Geng Deng, Yu Zhou, Hai‐Yuan Sun, Zhi‐Wu Yu, ChemPhysChem, 2015
Abstract The halogen bond, similar to the hydrogen bond, is an important noncovalent interaction and plays important roles in diverse chemistry‐related fields. Herein, bromine‐ and iodine‐based halogen‐bonding interactions between two benzene derivatives (C6F5Br and C6F5I) and dimethyl ...
23-Jun-2015 | Christian Rösner; Ulrich Hennecke, Organic Letters, 2015
Organic Letters DOI: 10.1021/acs.orglett.5b01315
17-Jun-2015 | Per Martin Björemark, Johan Jönsson, Mikael Håkansson, Chemistry - A European Journal, 2015
Abstract Syntheses of [Co(bpy)3]2+ yield racemic solutions because the Δ‐ and Λ‐enantiomers are stereochemically labile. However, crystallization and attrition‐enhanced deracemization can give homochiral crystal batches of either handedness in quantitative yield. Subsequently, solvent‐free ...
17-Jun-2015 | Zhigang Shuai, Qian Peng, Yujun Xie, Tian Zhang, Zhen Li, Yuanping Yi, Chemistry - An Asian Journal, 2015
The photophysical properties of a series of silole derivatives, with hydrogen (TPS), bromine (BrTPS), and conjugated phenyl (HPS), triphenylsilyethynyl (BTPES) and dimethylfluorene (BFTPS) substituents at 2, 5‐positions in both gas and aggregate phases have been investigated computationally by ...
16-Jun-2015 | Kojiro Fujimura; Makoto Ouchi; Mitsuo Sawamoto, Macromolecules, 2015
Decamethylferrocene (FeCp*2) was found to be an effective cocatalyst for metal-catalyzed living radical polymerization with FeBr2/n-Bu4NBr as the main catalyst. For polymerization of methyl methacrylate (MMA) with a bromine-type initiator, the conversion was limited in the absence of FeCp*2, ...
