Claim 15:
16. A method of producing a mono alkyl tin halide from an alkyl tin compound, the method comprising:
providing the alkyl tin compound;
adding a Lewis acid catalyst to the alkyl tin compound to create a reaction mixture;
heating the reaction mixture; and
dosing a hydrogen halide into the reaction mixture to convert the alkyl tin compound into a raw product containing mono alkyl tin halide,
