A transition metal free stannylation reaction of alkyl bromides and iodides with hexamethyldistannane has been developed. This protocol is operationally convenient and features a rapid reaction and good functional group tolerance. A wide range of functionalized primary and secondary alkyl and benzyl trimethyl stannanes are prepared in moderate to excellent yields. The success of the gram-scale procedure

series of meta- and para-substituted benzyltrimethylstannanes have been prepared and their reactions with sulfur dioxide in methanol solvent at 30° have been studied kinetically by an 1H NMR method. Insertion occurs exclusively into the benzyl—tin bond, irrespective of substituent (m- and p-CH3, m- and p-CF3, m- and p-Cl, m- and p-OCH3), and the reaction exhibits good second-order kinetics for at least
