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.

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
Hydrogen peroxide can also be used as the oxidant. [2] Ph 2 S 2 is rarely prepared in the laboratory because it is inexpensive, and the precursor has a disagreeable odour. Like most organic disulfides, the C–S–S–C core of Ph 2 S 2 is non-planar with a dihedral angle approaching 85°. [3] Ball-and-stick model of diphenyl disulfide.
DCDPS is synthesized via sulfonation of chlorobenzene with sulfuric acid, often in the presence of various additives to optimize the formation of the 4,4′-isomer: . ClC 6 H 5 + SO 3 → (ClC 6 H 4) 2 SO 2 + H 2 O
Thioxanthone can be prepared by the reaction of diphenyl sulfide with phosgene in the presence of catalytic aluminium chloride. [2] This synthesis can be seen as a special case of the Friedel-Crafts acylation. The reduction product is thioxanthene.
4,6-Dimethyldibenzothiophene is an organosulfur compound with the formula (C 6 H 3 CH 3) 2 S.It is one of several dimethyl derivatives of benzothiophene.The compound is of particular interest as an organosulfur contaminant in petroleum that is recalcitrant.
This article lists veterinary pharmaceutical drugs alphabetically by name. Many veterinary drugs have more than one name and, therefore, the same drug may be listed more than once. Abbreviations are used in the list as follows: INN = International Nonproprietary Name; BAN = British Approved Name; USAN = United States Adopted Name
