Studies in group IV organometallic chemistry XXXI. Organotin hydride adducts with tin atoms in α,β- or β,β-positions

Abstract

The structure of several organotin hydride adducts which previously were assumed to contain tin atoms in β,α-positions (β-addition followed by α-addition) has been reinvestigated. As appeared from NMR spectroscopy the greater part of these linear molecules, polymers and heterocycles are in fact β,β-adducts. Mechanistic aspects of the formation of these compounds have been discussed.
