SYNTHESIS AND REACTIVITY OF DISULFONYL CHLORIDES FROM 1,1,1-TRICHLORO-2,2-BIS(4-CHLOROPHENYL)ETHANE
Novakovski, E.
, p. 1319 - 1322 (2007/10/02)
The corresponding disulfonyl chlorides, sodium disulfonates, and disulfonamides were obtained from 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane and its analogs by successive chlorosulfonation, hydrolysis, salting out, and ammonolysis.
