IUPAC Name:phenyldisulfanylbenzene
Synonyms:PHENYL DISULFIDE;BIPHENYL DISULFIDE;PHENYL DISULPHIDE;DIPHENYL DISULFIDE;DIPHENYL DISULPHIDE;DIPHENYLDISULPIDE;FEMA 3225;AKOS 94361
Uses
PHENYL DISULFIDE with its cas registry number(882-33-7) could be used as a pesticide, medicine, dyes intermediates.
Production
Ph2S2 is usually prepared by the oxidation of thiophenol:
2PhSH + I2 → Ph2S2 + 2HI
Hydrogen peroxide can also be used as the oxidant.Ph2S2 is rarely prepared in the laboratory because it is inexpensive, and the precursor has a disagreeable odour.
Like most organic disulfides, the C2S2 core of Ph2S2 is non-planar with a dihedral angle approaching 85°.
