Phenylmethanesulfonyl chloride is an aliphatic sulfonyl chloride. It reacts with triethylamine in methylene chloride or ether to yield trans-stilbene and cis diphenylethylene sulfone. Its reaction with 1,1-bis(diethylamino)ethane has been studied. Addition of phenylmethanesulfonyl chloride to 1,3-diphenyl-2-pyrrolidinopropene in the presence of water was studied. |
