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.
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.
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
Like many other sulfur-containing compounds, volatile sulfides have foul odors. [1] A sulfide is similar to an ether except that it contains a sulfur atom in place of the oxygen. The grouping of oxygen and sulfur in the periodic table suggests that the chemical properties of ethers and sulfides are somewhat similar, though the extent to which ...
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.
Thioxanthone is a heterocyclic compound that is a sulfur analog of xanthone.. Thioxanthone can be prepared by the reaction of diphenyl sulfide with phosgene in the presence of catalytic aluminium chloride. [2]
The vinyl sulfone parabase ester can be used as a diazo component in the preparation of azo dyes. [1] A further possibility is the condensation reaction of parabase ester with a chlorine or fluorotriazine residue, which in turn can be linked to any chromophore via a further amino group.
Exceptions include bisphenol S, P, and M. "Bisphenol" is a common name; the letter following denotes the variant, which depends on the additional substituents. Bisphenol A is the most popular representative of the group, with millions of metric tons produced globally in the past decade, often simply called "bisphenol". [3] [4] [5]
