Stable Five‐Coordinate Silicon(IV) Complexes with SiN₄X Skeletons (X=S, Se, Te) and SiX Double Bonds

Abstract

Silylenes: Reaction of the donor-stabilized silylene 1 with elemental sulfur, selenium, or tellurium led to the formation of 2 a-c [SiN(4)X skeletons (X = S, Se, Te)], the first stable five-coordinate silicon(IV) compounds with silicon-chalcogen double bonds (see figure).
