General description
Bis(4-chlorophenyl) disulphide can be synthesized from 4-chlorophenylthiol via oxidation.[1] It produces poly(p-phenylene sulfide), via thermolysis.[2] Bis(4-chlorophenyl) disulfide can also be prepared by a microwave assisted method involving the reaction between respective elemental sulfur and 1-chloro-4-iodobenzene in the presence of CuO nanopowder (catalyst).[3]
Application
Bis(4-chlorophenyl) disulfide may be used to synthesize non-symmetrical heterodimer 4-chlorophenyl-2′-nitrophenyl disulfide.[4]
