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 disulfide is usually prepared by the oxidation of thiophenol: . 2 PhSH + I 2 → Ph 2 S 2 + 2 HI 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.
Disulfide is also used to refer to compounds that contain two sulfide (S 2−) centers. The compound carbon disulfide , CS 2 is described with the structural formula i.e. S=C=S. This molecule is not a disulfide in the sense that it lacks a S-S bond.
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
[7] hydrogen peroxide is a typical oxidant, but periodate has also been used. [8] In these oxidations, care is required to avoid over oxidation to form the sulfone. For example, dimethyl sulfide is oxidized to dimethyl sulfoxide and then further to dimethyl sulfone. Unsymmetrical sulfides are prochiral, thus their oxidation gives chiral ...

In the laboratory, diphenylphosphine is a common intermediate. It can be deprotonated to give diphenylphosphide derivatives: [2] Ph 2 PH + n BuLi → Ph 2 PLi + n BuH. The preparation of phosphine ligands, Wittig-Horner reagents, and phosphonium salts are commonly accomplished by alkylating diphenylphosphine.
In the presence of aluminium chloride (AlCl 3), S 2 Cl 2 reacts with benzene to give diphenyl sulfide: 8 S 2 Cl 2 + 16 C 6 H 6 → 8 (C 6 H 5 ) 2 S + 16 HCl + S 8 Anilines (1) react with S 2 Cl 2 in the presence of NaOH to give 1,2,3-benzodithiazolium chloride (2) ( Herz reaction ) which can be transformed into ortho -aminothiophenolates (3 ...
