✦ Synopsis

The reduction of methyl, ethyl, n-propyl and n-butyl iodides has been studied at a tin cathode in dimethylformamide. The major product from the reduction of methyl iodide is tetramethyl tin but from ethyl, propyl and butyl iodides it is butane, hexane and oxtane respectively. Also as the size of the alkyl group increases the yield of tin alkyl decreases and yield of monomer hydrocarbon (i.e. ethane, propane and butane respectively) becomes more important. Steady state, cyclic voltammetric and pulse experiments have been used to study these reductions. The factors which determine the change in the products with changes in the electrode material and the structure of the alkyl iodide are discussed. * On leave from Laboratorio di Polarografia ed Electrochimica Preparativa de1 C.N.R., Padova, Itaty.

In ethanolic solution methyl iodide reduces on tin cathodes to tetramethyltin but ethyl halides do not yield the corresponding tin ethyls except in insignificant yields. Increases in alkyl halide concentrations improve the yields of tin alkyls and also increase the passivation of the surface towards
