Abstract
The preparation of alkyl tin halides is carried out by direct conversion of a gaseous lower aliphatic halide with a stannous halide in the presence of a nitrogenous solvent of the acid amide type at substantially atmospheric pressure. The acid amide solvent is present in quantities of approximately 1-4 mol per mol stannous halide. This reaction proceeds without the production of any trialkyl tin compounds as by-products.
