Notizen / Notes. Investigation on the Product from Monobutyltin(IV) Compounds and Benzoyl(thiobenzoyl)methane: a 1,3,2λ5,4λ5‐Dithiadistannetane

Abstract

Butyltin triisopropoxide reacts with benzoyl(thiobenzoyl)methane (LH) to yield BuSn(S)L and an organic sulfide 2 instead of the expected BuSnL3. The use of other butyltin(IV) starting materials invariably leads to the same products. From an X‐ray structure determination the tin sulfido complex is found to be a centrosymmetric dimer, [BuSn(S)L]2 (1) with a planar four‐membered Sn2S2 ring containing pentacoordinated tin atoms.
