Abstract

Abstract By heating carboxamides with O, O-diethyl dithiophosphoric acid, 1, at 110-125 C the corresponding thiocarboxamides and/or ethyl dithiocarboxylates were formed. ortho- Substituted N, N-dimethylbenzamides only gave the corresponding thiocarboxamides. By using O, O-dipropyl dithiophosphoric acid and O, O-diisopropyl dithiophosphoric acid, thiocarboxamides were also prepared, and the corresponding propyl and isopropyl ...
