Abstract
A process is disclosed for the direct production of organotin halides, particularly triorganotin halides by the reaction of elemental tin and an organotin halide in the presence of a reagent amount of an `onium compound of the general formula Cat.sup.+ X.sup.-. Cat.sup.+ X.sup.- may represent a quaternary ammonium or phosphonium group or a ternary sulphonium group, or may also represent a complex of an alkali metal or alkaline earth metal with a polyoxygen compound. High yields of triorganotin halide product are obtained in contrast to results of reactions wherein Cat.sup.+ X.sup.- is present in only catalytic amounts.
