Functionalization of highly electrophilic N-(2,2,2-trichloroethylidene)- and N-(2,2-dichloro-2-phenylethylidene) arenesulfonamides with dithiooxamide
摘要:
Depending on the reactant ratio, dithiooxamide (ethanedithioamide) reacted as N-nucleophile or N,N'-binucleophile with highly electrophilic aldimines, N-(2,2,2-trichloroethylidene)- and N-(2,2-dichloro-2-phenylethylidene)arenesulfonamides, to give the corresponding mono- or bis-adducts, N-[2-polychloro-1-(arylsulfonylamino) ethyl]ethanedithioamides or N,N'-bis[2-polychloro-1-(arylsulfonylamino)ethyl]ethanedithioamides, in good yield.
