  Cu-deposits on Mg metal surfaces promote electron transfer reactions

  摘要：

  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.

  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.
