Results of a kinetic study of the protodestannylation of a number of vinyltrialkyltins and substituted vinyltrialkyltins by hydrogen chloride in methanol-water are reported. The relative rate constants are consistent with a steric sequence and open transition state. Substitution of a methyl group or phenyl group on the P-carbon leads to rate enhancement but in lesser magnitude than in the iodostannylation reaction. The effect of the concentration of water in ...
