Abstract

The preparation of allyltrimethylsilanes by regioselective pathways is described. Treatment of (E)-l-chloro-Zalkenes with a reagent prepared from 1 equiv each of trimethylsilyllithium and copper (1) iodide in hexamethylphosphoramide to presumably form a (trimethylsily1) copper reagent affords 3-(trimethylsilyl)-l-alkenes in good to excellent yields with high regioselectivity. Treatment of these same 1-chloro-2-alkenes with (trimethylsily1) lithium ...
