ABSTRACT OF THE DISCLOSURE A process is disclosed for the direct pro- duction of organotin halides, particularly triorgano- tin 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+X-. Cat+X- may represent a quaternary am- monium 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 com- pound. High yields of triorganotin halide product are obtained in contrast to results of reactions wherein Cat+X- is present in only catalytic amounts.
