- New approach to the preparation of p-(1-cyanoethyl)arenesulfonamides by reaction of arylsulfonyl imines of polychloroacetaldehydes with acetone cyanohydrin
-
Reaction of N-(2,2,2-trichloroethylidene)- or N-(1-phenyl-2,2-dichloroethylidene)arenesulfonamides with acetone cyanohydrin in acetone in the presence of potassium carbonate led to the formation of N- (2,2,2-trichloro-1-cyanoethyl)- or N-(2-phenyl-2,2-dic

- N,N-DICHLOROARENESULFONAMIDES IN REACTION WITH 1,2-DICHLOROETHYLENE
-
The reaction of N,N-dichloroarenesulfonamides with cis- and trans-1,2-dichloroethylene under the conditions of free-radical initiation lead to the formation of the N-arylsulfonylimines of dichloroacetaldehyde and the products from their further transformation, i.e., 2,2-dichloro-1,1-di(arylsulfonylamino)ethanes.The arylsulfonylimines of chloral, arenesulfonamides, trichloroethylene, and the products from chlorination of 1,2-dichloroethylene are formed as side products.

- REACTION OF TRICHLOROETHYLENE WITH N,N-DICHLOROARENESULFONAMIDES IN THE PRESENCE OF LEWIS ACIDS
-
The reaction of N,N-dichloroarenesulfonamides with trichloroethylene in the presence of ionic catalyst (SnCl4 and AlCl3) leads to N-(2,2,2-trichloroethyliden)-arenesulfonamides and the products of the subsequent conversion, namely, N-(2,2,2-trichloro-1-arenesulfonamidoethyl)arenesulfonamides and N-(2,2,2-trichloro-1-hydroxyethyl)arenesulfonamides.
