| Questions And Answer | Back Directory | [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. |
| Hazard Information | Back Directory | [Uses]
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. | [General Description]
