ABSTRACT:
Amides of phosphorus-containing acids are reacted with sulphenyl halides to give phosphorus-containing acid amides in which one or more of the nitrogen atoms carries the appropriate substitutent attached through a sulphur atom. These substituted amides are inhibitors of premature vulcanisation in rubbers. The most effective compounds are arylamides substituted by secondary alkylthio groups.
