Oxidative Addition of Diethylchalcogenanes to Lappert's Germylene and Stannylene

Oxidative addition of diethyldichalcogenanes Et2E2 (E = S, Se, Te) to bis[his(trimethylsilyl]amido]germylene and -stannylene M[N(SiMe3)(2)](2) (M = Ge, Sn) proceed with formation of the COrresponding bis(ethylchalcogena(o)germanes (Me3Si)(2)N)(2)Ge(EEt)(2) [E = S (1), Se (2), Te (3)] and -stannanes (Me3SO2N)(2)Sn(EEt)(2)[E = S (4), Se (5), Te (6)]. The solid state structures of 1-6 were determined by single-crystal X-ray diffraction.
