Abstract

A new application of zincate [(THF) Li(TMP)(Bu-t) Zn(Bu-t)] (1) in alkali-metal mediated zincation (AMMZn) is reported by isolating and structurally defining the first intermediates of direct lateral zincation (DIZn) of trimethyl(phenoxy) silane (2) both of which adopt novel six-element {ZnCSiOLiN} ring structures.
