Configurational assignment of N-arylsulfonylimines of α- polychloroaldehydes

Configurational assignment of seven synthesized N-arylsulfonylimines of α-polychloroaldehydes has been carried out by means of experimental measurements and high-level ab initio calculations of their 13C- 13C, 13C-1/

Alkylation of phenols with N-(2,2,2-trichloroethylidene)- and N-(2,2,2-trichloroethyl)arenesulfonamides

N-(2,2,2-Trichloroethylidene)- and N-(2,2,2-trichloroethyl)arenesulfonamides react with phenol, 2-chlorophenol, and 2-methylphenol in the presence of oleum or sulfuric acid to give the corresponding 4-(2,2,2-trichloro-1-arylsulfonylaminoethyl)phenols in g

N-(Trichloroethylidene)arenesulfonamides in Reactions with Allyl Alcohol and Allylamine

N-(Trichloroethylidene)arenesulfonamides react with heat evolution with allyl alcohol and allylamine to form products of nucleophilic addition at the C=N bond, N-[1-(allyloxy)-2,2,2-trichloroethyl]-and W-[1-(allylamino)-2,2,2-trichloroethyl]arenesulfonamides in a high yield.

N-(2,2,2-TRICHLOROETHYLIDENE)ARENESULFONAMIDES AND N-(2,2,2-TRICHLOROETHYLIDENE)ETHOXYFORMAMIDES IN REACTIONS WITH AMINES

The reaction of highly electrophilic N-(2,2,2-trichloroethylidene)arenesulfonamides with primary alkylamines and arylalkylamines leads to the formation of the addition products N-arenesulfonamides.These compounds are unstable, and this is due to the presence of the three electronegative substituents at the methine carbon atom.More basic dialkylamines lead to haloform decomposition of the N-(2,2,2-trichloroethylidene)arenesulfonamides and give high yields of dialkylarenesulfonylformamidines.At the same time dialkylamines add to N-(2,2,2-trichloroethylidene)etoxyformamide, forming N-ethoxyformamide.In reaction with trichloroethylideneethoxyformamide dimethylethanolamine forms the O-amidoalkylation product, i.e., N-ethoxyformamide, but its reaction with N-(2,2,2-trichloroethylidene)arenesulfonamide gives rise to its haloform decomposition with the formation of the corresponding arenesulfonamide.

N-(2,2,2-TRICHLOROETHYLIDENE)ARENESULFONAMIDES FROM N,N-DICHLOROARENESULFONAMIDES AND TRICHLOROETHYLENE IN REACTIONS WITH BIFUNCTIONAL COMPOUNDS

The reaction of highly electrophilic N-(2,2,2-trichloroethylidene)arenesulfonamides with bifunctional nucleophiles (mercaptoethanol, ethylene glycol, monoethanolamine, and mercaptoethylamine hydrochloride) was studied.In the reactions with mercaptoethanol

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.

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.
