Chlorobenzene (abbreviated PhCl) is an aryl chloride and the simplest of the chlorobenzenes, consisting of a benzene ring substituted with one chlorine atom. Its chemical formula is C 6 H 5 Cl. This colorless, flammable liquid is a common solvent and a widely used intermediate in the manufacture of other chemicals.

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. It can also be produced by chlorination of diphenylsulfone. [3]
For example, the chloro derivative C 6 H 5 Cl is normally called chlorobenzene, although it could be called phenyl chloride. In special (and rare) cases, isolated phenyl groups are detected: the phenyl anion ( C 6 H − 5 ), the phenyl cation ( C 6 H + 5 ), and the phenyl radical ( C
Other methods afford the compound less efficiently include the chlorination of 1,3-dinitrobenzene, nitration of o-nitrochlorobenzene and the dinitration of chlorobenzene. [3] By virtue of the two nitro substituents, the chloride in DNCB is particularly susceptible to nucleophilic substitution, at least relative to simple chlorobenzene. In this ...
Hexachlorobenzene, or perchlorobenzene, is an aryl chloride and a six-substituted chlorobenzene with the molecular formula C 6 Cl 6. It is a fungicide formerly used as a seed treatment, especially on wheat to control the fungal disease bunt. Its use has been banned globally under the Stockholm Convention on Persistent Organic Pollutants. [6]
4,4’-Dichlorobenzophenone is prepared by the acylation of chlorobenzene with 4-chlorobenzoyl chloride. The conversion is typically conducted in the presence of an aluminium chloride catalyst in a petroleum ether solvent. ClC 6 H 5 C(O)Cl + C 6 H 5 Cl → (ClC 6 H 4) 2 CO + HCl
