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 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.
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 ]
The S-S bond length is 2.03 Å in diphenyl disulfide, [1] similar to that in elemental sulfur. Two kinds of disulfides are recognized, symmetric and unsymmetric. Symmetrical disulfides are compounds of the formula RSSR. Most disulfides encountered in organo sulfur chemistry are symmetrical disulfides.
The structure of a sulfone Dimethyl sulfone, an example of a sulfone. In organic chemistry, a sulfone is a organosulfur compound containing a sulfonyl (R−S(=O) 2 −R’) functional group attached to two carbon atoms.
Sulfonyl groups can be reduced to the sulfide with diisobutylaluminium hydride (DIBALH). Lithium aluminium hydride (LiAlH 4) reduces some but not all sulfones to sulfides. [1]: 1851 In inorganic chemistry, when the group −S(=O) 2 − is not connected to any carbon atoms, it is referred to as sulfuryl. [3]
Trichloromethanesulfenyl chloride is a stable sulfenyl chloride. Sulfenyl chlorides are typically prepared by chlorination of disulfides: [2] [3]. R 2 S 2 + Cl 2 → 2 R−SCl. This reaction is sometimes called the Zincke disulfide reaction, in recognition of Theodor Zincke.
