General Description

Bis(4-chlorophenyl) disulphide can be synthesized from 4-chlorophenylthiol via oxidation. It produces poly(p-phenylene sulfide), via thermolysis. 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).
