HCID 30183422-[(4-Chlorophenyl)sulfanyl]benzonitrile

Procedure

Method of preparing 2-chloro-thioxanthone which comprises reacting an alkali metal derivative of 4-chloro-thiophenol with 2-chloro-benzonitrile in an organic solvent to form 2-(4'-chloro-phenylthio)-benzonitrile, hydrolyzing said 2-(4'-chloro-phenylthio)-benzonitrile to form 2-(4'l -chloro-phenylthio)-benzoic acid and cyclising said 2-(4'-chloro-phenylthio)-benzoic acid by dehydration to produce 2-cloro-thioxanthone.
