摘要

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