Trichloromethanesulfonyl chloride Chemical Properties,Usage,Production
Application
Trichloromethanesulfonyl chloride can be used as a pharmaceutical synthesis intermediate. Perfluoroiodoalkanes and bromoalkanes undergo sulfinization-deiodination and debromination reactions with sodium dithionite under appropriate conditions, while perfluorochloroalkanes do not react under similar conditions. However, carbon tetrachloride and 1,1,1-trichloropolyfluoroalkanes can undergo sulfinization-dechlorination reactions with sodium dithionite. Trichlorobromomethane and trichloroiodomethane react under similar conditions to yield sulfinized debromination and deiodination products, respectively.
General Description
Trichloromethanesulfonyl chloride is an efficient free radical chlorinating agent. It reacts with pent-4-enylcobaloximes in inert solvent under tugsten lamp irradiation to yield 2-(β,β,β- trichloroethyl)sulfolanes. It also reacts with trimethylsilyl enol ethers of acetophenones in the presence of a ruthenium (II) phosphine complex to yield 1-aryl-3,3-dichloropropen-1-one and α-chloroacetophenones.
