Dibenzyl sulfide is a symmetrical thioether. It contains two C 6 H 5 CH 2 - (benzyl) groups linked by a sulfide bridge. It is a colorless or white solid that is soluble in nonpolar solvents.
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.
Tris(dimethylamino)phosphine is an organophosphorus compound with the formula P(NMe 2) 3 (Me = methyl).It is a colorless oil at room temperature, and is one of the most common aminophosphines.
Benzyl is most commonly abbreviated Bn. For example, benzyl alcohol can be represented as BnOH. Less common abbreviations are Bzl and Bz, the latter of which is ambiguous as it is also the standard abbreviation for the benzoyl group C 6 H 5 C(O)−.
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.
In organic chemistry, a sulfide (British English sulphide) or thioether is an organosulfur functional group with the connectivity R−S−R' as shown on right. Like many other sulfur-containing compounds, volatile sulfides have foul odors. [ 1 ]
In chemistry, a disulfide (or disulphide in British English) is a compound containing a R−S−S−R′ functional group or the S 2− 2 anion.The linkage is also called an SS-bond or sometimes a disulfide bridge and usually derived from two thiol groups.
The 4S pathway is a sulfur-specific metabolic pathway of oxidative desulfurization that converts dibenzothiophene (DBT) into 2-hydroxybiphenyl and sulfite.It uses a total of four NADH molecules (three required by DszD to generate FMNH 2 and a fourth to regenerate the FMN-oxide byproduct of DszA) and three molecules of oxygen, thus producing NAD + and water as byproducts.
