  醇键合弱化螺旋硅烷催化剂的光氧化还原α-C-H烷基化的鉴定

  摘要：

  催化剂控制的位点选择性C（sp 3）-H官能化的发展是有机合成中的当前主要挑战。本文描述了DFT指导的五价硅酸盐种类的鉴定，它是一种新型的醇α-C-H键弱键化催化剂，以及光氧化还原催化剂和氢原子转移催化剂。特别是，马丁的螺硅烷促进了醇的α-CH烷基化。

  日期：2011.10

  Fluorolactonization of unsaturated carboxylic acids under action of the electrophilic reagent F-TEDA-BF4 in ionic liquids (ILs) has been studied. This reaction proceeds in ILs faster and provides a better stereoselectivity in comparison to acetonitrile as reaction media. Gem-difluorinated gamma-lactones have been synthesized by interaction of unsaturated carboxylic acids with F-TEDA-BF4 in ILs. (C) 2011 Elsevier Ltd. All rights reserved.
