Diphenyl sulfide is an organosulfur compound with the chemical formula (C
6H
5)
2S, often abbreviated as Ph
2S, where Ph stands for phenyl. It is a colorless liquid with an unpleasant odor. Diphenyl sulfide is an aromatic sulfide. The molecule consists of two phenyl groups attached to a sulfur atom.
Synthesis, reactions, occurrence
Many methods exist for the preparation of diphenyl sulfide. It arises by a Friedel-Crafts-like reaction of sulfur monochloride and benzene.[4]Diphenyl sulfide and its analogues can also be produced by coupling reactions using metal catalysts.[5] It can also be prepared by reduction of diphenyl sulfone.[6]
Diphenyl sulfide is a product of the photodegradation of the fungicide edifenphos.[7]
Diphenyl sulfide is a precursor to triarylsulfonium salts, which are used as photoinitiators. The compound can be oxidized to the sulfoxide with hydrogen peroxide.[8]
