Relevant academic research and scientific papers

N-chloro-N-(1,2,2,2-tetrachloro- and 1,2,2-trichloroethyl)-sulfonamides from N,N-dichlorosulfonamides and 1,2-polychloroethenes

N,N-Dichlorosulfonamides react with trichloroethylene and 1,2-dichloroethylene at a temperature not exceeding 20°C to afford unstable addition products, N-chloro-N-(1,2,2,2-tetrachloroethyl)- and N-chloroN-(1,2,2-trichloroethyl)sulfonamides. The latter undergo elimination of chlorine on heating, irradiation, or prolonged storage to give the corresponding N-(2,2-di- or 2,2,2-trichloroethylidene)arene(or trifluoromethane)- sulfonamides.

C- and N-amidotrichloroethylation of azoles

1H-Pyrazoles, triazoles, and imidazoles in reaction with ethoxycarbonylimine and arylsulfonylimines of chloral yield addition products, corresponding 1-(1-amidotrichloroethyl)azoles. Derivatives of 1-alkylpyrazoles and pyrazolones react with chloral 4-chl

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

C-amidoalkylation of the esters of aroxy- and arylthioacetic acids with trichloroethylidenarenesulfonamides

Esters of aroxyacetic and arylthioacetic acids react with chloral arenesulfonylimines in the presence of oleum affording in good yields the products of C-arenesulfonylamidoalkylation of the aromatic ring in 4 position.

Arylsulfonylaminoalkylation of indoles

Indole and its C- and N-methyl derivatives react with N-(2,2,2-trichloroethylidene)arenesulfonamides, yielding 3-(2,2,2-trichloro-1-arylsulfonylaminoethyl)indoles.

Transformations of N-(2,2,2-Trichloroethylidene)-arenesulfonamides

N-(2,2,2-Trichloroethylidene)arenesulfonamides take up at the double C=N bond benzyl and 2-propynyl alcohols and aromatic and unsaturated aliphatic carboxylic acids to give N-(2,2,2-trichloroethyl)-arenesulfonamides. Reactions of the title compounds with dibasic acids (oxalic, succinic, and adipic) result in formation of 1:1 and 2:1 addition products.

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-(2,2,2-TRICHLOROETHYLIDENE)ARENESULFONAMIDES IN REACTION WITH AZINES OF AROMATIC ALIPHATIC KETONES AND ALDEHYDES

The 1,3-dipolar cycloaddition of p-methoxybenzaldehyde azine to N-(2,2,2-trichloroethylidene)arenesulfonamide results in the formation of 2,6-di(4-methoxyphenyl)-3,7-diphenylsulfonyl-4,8-di(trichloromethyl)-1,3,5,7-tetraazabicyclooctane.The reactio

REACTION OF N,N-DICHLOROBENZENESULFONAMIDE WITH 2,2-DICHLOROVINYL ALKYL ETHERS

The reaction of N,N-dichlorobenzenesulfonamide with 2,2-dichlorovinyl alkyl ethers leads to N-(2,2,2-trichloro-1-alkoxyethyl)benzenesulfonamides with yields of 46-75percent.
