- C-phosphorylated N-(trichloroethylidene)sulfonamides: A new type of highly electrophilic imines
-
A convenient preparative approach to previously unknown, highly electrophilic C-phosphorylated N-arylsulfonylimines 1, based on fairly readily accessible α-phosphorylated sulfonamides 5, has been developed. Compounds 1 react with trialkyl phosphites or ethyl diphenylphosphinite in the aza-Perkow reaction scheme to give C,N-diphosphorylated N-dichlorovinylsulfonamides 8. On treatment with O- and S-nucleophilic agents (alcohols, thiols, thiophenols), 1 forms addition products 12 and 15, the functionalized derivatives of α-aminophosphonic acids, while interaction between 1 and mercaptoacetic acid proceeds with intramolecular cyclization of the intermediate adduct to produce the novel 2-phosphorylated thiazolidinones 17.

- INVESTIGATION OF THE MECHANISM OF THE REACTION OF N,N-DICHLOROBENZENESULFONAMIDE AND N,N-DICHLOROURETHANE WITH TRICHLOROETHYLENE BY THE 1H CINDP METHOD
-
The mechanism of the photochemical reaction of N,N-dichlorobenzenesulfonamide and N,N-dichlorourethane with trichloroethylene was studied by chemically induced dynamic polarization of nuclei and ESR.The presence of radical stages was demonstrated.Possible paths to the formation of the final products are suggested.
