alpha-Toluenesulfonyl chloride Usage And Synthesis

Chemical Properties

almost white crystalline powder

Uses

a-Toluenesulfonyl Chloride inhibits intracellular protein breakdown in the L1210 ascites leukemia in mouse. It also functions as a reagent for the protection of amino groups as benzylsulfonamides which can be cleaved off through reduction.

General Description

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.
