Procedure

U.S. Pat. No. 3,711,513 teaches the preparation of 1-chloro-thioxanthone by reacting 2,6-dichloro-benzonitrile with an alkali metal salt of thiophenol to obtain 2-chloro-6-phenylthio-benzonitrile, which is reacted with polyphosphoric acid to give 1-chloro-9-imino-thioxanthene, this latter product being hydrolysed to 1-chloro-thioxanthone.
