Abstract
Reduction of alkyl halides at a Sn cathode in results in mixed degrees of alkylation of this metal. Primary products include , , and/or reactive polytins containing these units. Final products depend on environment and tend to be complicated mixtures. A direct synthesis with good yields of dibutyltin oxide and dioctyltin oxide results from aerating the catholyte. A mixture of alkyltin halides is formed in an undivided cell by the interaction of anode and cathode products; other products include the tetraethylammonium alkylhalostannates. Factors governing the course of cathodic alkylation are discussed.
