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.
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 oxidation and reduction of protein disulfide bonds in vitro also generally occurs via thiol–disulfide exchange reactions. Typically, the thiolate of a redox reagent such as glutathione, dithiothreitol attacks the disulfide bond on a protein forming a mixed disulfide bond between the protein and the reagent. This mixed disulfide bond when ...
NEW YORK (Reuters) -A federal judge dismissed a U.S. Department of Justice lawsuit accusing eBay of violating environmental laws by allowing the sale of hundreds of thousands of harmful products ...
Disinfection by-products (DBPs) are organic and inorganic compounds resulting from chemical reactions between organic and inorganic substances such as contaminates and chemical treatment disinfection agents, respectively, in water during water disinfection processes.
Thiophenol is an organosulfur compound with the formula C 6 H 5 SH, sometimes abbreviated as PhSH. This foul-smelling colorless liquid is the simplest aromatic thiol.The chemical structures of thiophenol and its derivatives are analogous to phenols, where the oxygen atom in the hydroxyl group (-OH) bonded to the aromatic ring in phenol is replaced by a sulfur atom.
Chlorodiphenylphosphine is an organophosphorus compound with the formula (C 6 H 5) 2 PCl, abbreviated Ph 2 PCl. It is a colourless oily liquid with a pungent odor that is often described as being garlic-like and detectable even in the ppb range.
Diphenyl diselenide is the chemical compound with the formula (C 6 H 5) 2 Se 2, abbreviated Ph 2 Se 2. This yellow-coloured solid is the oxidized derivative of benzeneselenol . It is used as a source of the PhSe unit in organic synthesis .
