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.
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.
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
The book cited claims that DDT and other pesticides caused cancer and that their agricultural use was a threat to wildlife, particularly birds. Although Carson never directly called for an outright ban on the use of DDT, its publication was a seminal event for the environmental movement and resulted in a large public outcry that eventually led ...
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
Other names 1,2-Di(pyridin-2-yl)disulfane (not recommended) 2,2′-Dipyridyldisulfide ... It is also used in molecular biology as an oxidising agent, ...
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]
