Abstract3-Chlorosulfinylalkanoyl chlorides undergo cyclization into the corresponding five-membered mixed anhydrides (1,2-oxathiolan-5-one 2-oxides) under the action of sodium or mercury acetates. 2-Chlorosulfinylbenzoyl chloride gives 3H-2,1-benzoxathiol-3-one 1-oxide in high yield.
摘要 3-氯亚磺酰基链烷酰氯在乙酸钠或乙酸汞的作用下环化成相应的五元混合酸酐(1,2-oxathiolan-5-one 2-oxides)。2-氯亚磺酰基苯甲酰氯以高产率得到 3H-2,1-benzoxathiol-3-one 1-oxide。
