Chemical behavior of tris (trimethylsilyl) silamecarboxylates toward organolithium reagents was investigated. Treatment of triethylsilyl, triphenylsilyl, and methyl tris (trimethylsilyl) silanecarboxylate (1a-c) with organolithium reagents gave products which can be explained in terms of three types of reactions, the formation of lithium tris (trimethylsilyl) silanecarboxylate, abstraction of a trimethylsilyl group by the organolithium reagents, and ...
