Diphenyl sulfide is an organosulfur compound with the chemical formula (C₆H₅)₂S, often abbreviated as Ph₂S, 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 edit

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 triaryl sulfonium salts, which are used as photoinitiators. The compound can be oxidized to the sulfoxide with hydrogen peroxide.^[8]
