Abstract

Regioselective methods for allene hydrosilylation have been developed, with regioselectivity being governed primarily by the choice of metal. Alkenylsilanes are produced via nickel catalysis with larger N-heterocyclic carbene (NHC) ligands, and allylsilanes are produced via palladium catalysis with smaller NHC ligands. These complementary methods allow either regioisomeric product to be obtained with exceptional regiocontrol.

摘要

已开发出用于丙炔硅氢化的区域选择性方法,区域选择性主要由金属的选择决定。使用较大的 N-杂环卡宾 (NHC) 配体通过镍催化生成烯基硅烷,而使用较小的 NHC 配体通过钯催化生成烯丙基硅烷。这些互补的方法允许使用特殊的区域控制获得任一区域异构体产物。
