Triallylmethylstannane, diallylmethallylmethylstannane, allyldimethallylmethylstannane, and trimethallylmethylstannane were produced by the reaction of triallylstannyllithium with methallyllithium followed by treatment with iodomethane. The formation of similar mixture of such stannanes was also observed when trimethallylstannyllithium was treated with allyllithium and iodomethane successively. These results indicate that the reaction of tri(substituted allyl)stannyllithium with (substituted allyl)lithium forms the equilibrium mixture of tri(substituted allyl)stannyllithiums having all the possible combinations of substituents.
