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 S-S bond length is 2.03 Å in diphenyl disulfide, [1] similar to that in elemental sulfur. Two kinds of disulfides are recognized, symmetric and unsymmetric. Symmetrical disulfides are compounds of the formula RSSR. Most disulfides encountered in organo sulfur chemistry are symmetrical disulfides.
Diphenyl disulfide is the chemical compound with the formula (C 6 H 5 S) 2. This colorless crystalline material is often abbreviated Ph 2 S 2. It is one of the more commonly encountered organic disulfides in organic synthesis. Minor contamination by thiophenol is responsible for the disagreeable odour associated with this compound.

The company says it continues to stand by the safety of its products. In 2019, the FDA found asbestos in cosmetics sold by Claire's Stores, prompting recalls by the retailer and Beauty Plus Global.
They are useful shelf-stable precursors to more reactive organoselenium reagents such as selenols and selanyl halides. Best known in organic chemistry is diphenyldiselenide, prepared from phenylmagnesium bromide and selenium followed by oxidation of the product PhSeMgBr. [8]
Diphenyl sulfone is an organosulfur compound with the formula (C 6 H 5) 2 SO 2.It is a white solid that is soluble in organic solvents.It is used as a high temperature solvent. Such high temperature solvents are useful for processing highly rigid polymers, e.g., PEEK, which only dissolve in very hot solve
