Chemistry of Heavy Carbene Analogues, R2M (M = SI, Ge, Sn). 7.1 A New and Convenient Source for Stannylenes, R2Sn: 1,2-Bls(phenylthlo)tetramethyldlstannane, Me2(PhS)Sn-Sn(SPh)Me2

Stannylene extrusion/insertion equilibria, R2XSn-SnXR2 = R2SuX2 + R2Sn, are found and investigated for X = Br and SPh, The Sn-Br and Sn-SPh bonds are efficient stannyleno scavengers. Me2(PhS)SnSn(SPh)Me2 is a convenient source both for thermal and photochemical stannylenoid reactions, giving 1,3,2-dixoastannolanes on reaction with 2 molar of aldehyde or 1,3,2-dioxastannolenes by reaction with α-diketones such as α-naphthoquinone, biacetyt or benzil. The saturated hetorocycles can be converted by acetyl chloride to diacetates of glycoles (under preservation of the D,L/meso relation). The unstaturated rings give diacetates of Z enediols.
