Results The reaction of ethylene oxide with methyl chlorosulfinate in benzene at 0'gave 70.8% of 0-chloroethylmethyl sulfite7 for 20 min. The results obtained from a variety of epoxides are shown in Table I; the preferential attack of the sulfinyl sulfur of methyl chlorosulfinate by epoxides seems to be predictable from the fact that methanesulfinyl chloride is known to react with ethylene oxide yielding the corresponding sulfinate ester. 8 ...
