Summary 1. Triphenylarsine and tri-o-tolylarsine have been condensed with N1- potassiochloro-"-acetylsulfanilamide to yield the corresponding hydrated arsinimines, while tri-p-tolylarsine yields the unhydrated arsinimine. 2. Several triarylarsine dihydroxides (arsine oxide hydrates) have been condensed with sulfanilamide or N4-acetylsulfanilamide to yield hydrated arsinimines.
