ChemInform Abstract: Hydrolysis of N-(2,2,2-Trichloroethyl)arenesulfonamides
Autor: T. V. Kashik, Mirskova Anna N, Igor B. Rozentsveig, Galina G. Levkovskaya
Publikováno v: ChemInform. 32
The direction of alkaline hydrolysis of N-(2,2,2-trichloro-1-R-ethyl)arenesulfonamides depends on the R substituent in the α-position with respect to the nitrogen atom. Substituents R having an n-donor heteroatom X promote cleavage of the C-N and C-
