Abstract

Abstract The reaction of [2, 2-bis (trimethylsilyl) ethyl]-and [2, 2-bis (trimethylgermyl) ethyl]- trimethylammonium iodides (3a and 3c) with n-butyllithium gives N-[(trimethylsilyl) methyl]- and N-[(trimethylgermyl) methyl] dimethylamines (5a and 5b), respectively. A mixture of 5a and 5b is obtained from the reaction of [2-(trimethylgermyl)-2-(trimethylsilyl) ethyl] trimethylammonium iodide (3b). Use of lithium diisopropylamide in place of n-butyllithium ...
