Abstract
2-Phenylthio-3-chlorosulfolane instead of the expected phenylsulfonylchlorosulfolane was isolated by the reaction of 2-sulfolene with benzenesulfonyl chloride at 180 deg C, catalyzed by a mixture of cuprous chloride and triethylamine hydrochloride. Oxidation of this product with hydrogen peroxide in acetic acid gave 2-phenylsulfonyl-2-sulfolene, the structure of which was proved by the IR and PMR spectra.
