Amides of phosphorus-containing thioacids are reacted with sulphenyl halides to give phosphorus-containing thioacid amides in which one or more of the nitrogen atoms carries a substituent attached through a sulphur atom. These substituted amides are inhibitors of premature vulcanisation in rubbers. The most effective compounds carry a secondary alkylthio or cycloalkylthio on each nitrogen atom.
