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
A number of allylic, allenylic and 2-propynylic (R′) derivatives of tin of the type R3SnR′ have been synthesized, and shown to undergo ready insertion of sulfurdioxide into the SnR′ bond. Rearrangement accompanies insertion so that the products have the alternate allylic, 2-propynylic and allenylic structures respectively. Di-insertion occurs only when groups attached to tin are quite susceptible
