Cp2TiCl2-Catalyzed Regio- and Chemoselective One-Step Synthesis of γ-Substituted Allylsilanes from Terminal Alkenes Using Dianion-Type Zincate (SiSiNOL-Zn-ate)
journal contribution
posted on 2005-09-28, 00:00 authored by Shinji Nakamura, Masanobu Uchiyama, Tomohiko OhwadaA regio-/chemoselective silylation reaction of various functionalized terminal alkenes in the presence of titanocene dichloride, based on a newly designed dianion-type zincate, was developed. The present silylation of terminal alkenes is a powerful tool for the one-pot generation of regiocontrolled functionalized allysilanes, which are available for various transformation reactions, such as hydroxyalkylation, epoxidation, and hydroboration.
