Abstract

Abstract A number of allylic, allenylic and 2-propynylic (R′) derivatives of tin of the type R 3SnR′ have been synthesized, and shown to undergo ready insertion of sulfur dioxide into the SnR′ 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 to electrophilic cleavage. NMR data for the compounds are reported.
