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.

Chlorination of beta-thiolactones with chlorine or sulfuryl chloride in acetic anhydride at a reactant ratio (PR) of 1:2:1 gives beta-(chlorosufinyl)alkanoyl chlorides in 75-89% yields. Oxidative chlorination of beta-thiolactones with RR of 1:3:2 affords beta-(chlorosulfinyl)alkanoyl chlorides and cyclic sulfinic anhydrides (1,2-oxathiolan-5-one 2-oxides). The optimum PR for the preparation of 1,2-oxathiolan-5-one 2-oxides is 1:2:2. Hydrolysis of alpha-chloro-beta-(chlorosulfinyl)carbonyl chlorides has given novel alpha-chlorinated sulfinocarboxylic acids.
