A direct, single synthetic homologative transformation of halostannanes into mono- or di-substituted methyl analogues is documented. Critical for the success of the operation is the excellent nucleophilicity of carbenoid-like methyllithium reagents (LiCHXY, X, Y = halogen, OR, and CN): by simply individuating the reagents’ substitution pattern, the desired functionalized fragment is delivered to the

these can then be reduced by trialkyltin hydrides or by lithium aluminium hydride to give the di- and mono-halogenomethyltin compounds, R3Sn·CHX2 and R3Sn·CH2X, respectively. Some properties and reactions of these products have been investigated.
