The behaviour of some substituted silacyclobutanes with respect to sulfur dioxide is studied. The alkylated, arylated and alkoxylated derivatives of silacyclobutane react with SO2 to give the first “silasultines” (2-oxo-4-sila-1,2-oxathianes). The structure and the configurational analysis of the insertion products are proved by chemical and physicochemical ways. The mechanism of the SO2 insertion
