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
研究了一些取代的硅杂环丁烷相对于二氧化硫的行为。甲硅烷基环丁烷的烷基化,芳基化和烷氧基化衍生物与SO 2反应,生成第一个“西拉苏啶”(2-oxo-4-sila-1,2-oxathianes)。通过化学和物理化学方法证明了插入产物的结构和构型分析。讨论了SO 2插入的机理。
