Single-step conversion of silathiogermylene to germaacid anhydrides: unusual reactivity

Surendar Karwasara et al. Chem Commun (Camb). .

Abstract

A novel silathiogermylene [Bu(I)2(ATI)GeSSiMe3] (2) containing a reactive Ge(II)-SSiMe3 moiety showed an unusual reaction when treated with elemental selenium and sulfur to afford the germaacid anhydrides [{Bu(I)2(ATI)Ge(Se)}2Se] (3) and [{Bu(I)2(ATI)Ge(S)}2S] (4) in excellent yields, respectively. This single-step conversion of compound 2 to compounds 3 and 4 involves condensation along with insertion and oxidative addition reactions and such reactivity of a germylene with elemental chalcogens is observed for the first time.
