  钯催化的芳基卤化物与芳基二氟甲基三甲基硅烷的芳基二氟甲基化

  摘要：

  钯催化的芳基卤化物与芳基二氟甲基三甲基硅烷的偶联被证明可形成二芳基二氟甲烷。钯的简单二烷基（二甲氧基苯基）膦配体在还原消除过程中稳定了钯和二氟苄基配体之间的π相互作用，并且钴催化的硅烷合成使该反应能够形成多种产物，包括具有生物活性的产物。

  Mg–Cu bimetal system for selective CF bond activation

  摘要：

  Bimetal system of Mg-CuCl I in DMI for selective C-F and C-Cl bonds activation has been examined. This article involves (1) a short overview of bimetal system of Mg-metals for selective C-F bond activation, (2) C-F bond activation of alkyl trifluoroacetates leading to alkyl difluoro(trimethylsilyl)acetates via difluoroketene silyl acetal, (3) selective C-Cl bond activation of 3- and 4-chloropentafluoroethylbenzenes, (4) C-F bond activation of substituted benzotrifluorides and (5) microscopic observation of an active site of magnesium surface formed in Mg-CuCl system and elucidation of reaction mechanism of C-Cl and C-F bond activation at the active site.

• Cu-deposits on Mg metal surfaces promote electron transfer reactions

  日期：2012.1

  The enhancement of the electron transfer processes in the Grignard reagent formation-type ring silylation and the defluorination-silylation of perfluoroalkyl benzenes by Cu(0)-deposited Mg metal were confirmed. Microscopic analysis and substituent effects implied a different reduction process in the presence of Cu-deposited Mg metal than in the presence of bare Mg metal. (C) 2011 Elsevier Ltd.

  Palladium-catalyzed coupling of aryl halides with aryldifluoromethyl trimethylsilanes is shown to form diaryl difluoromethanes. A simple dialkyl(dimethoxyphenyl)phosphine ligand for palladium, stabilizing π-interactions between palladium and the difluorobenzyl ligand during reductive elimination, and a cobalt-catalyzed synthesis of the silanes enabled the reaction to form diverse products, including
