Product Name:Phenylsulfenylchloride
CAS Number:931-59-9
Molecular formula:C6H5ClS
Molecular Weight:144.62

To a flask containing 32.7 gm (0.15 mole) of diphenyl disulfide dissolved in 100 ml of dichloromethane containing 3 ml of pyridine is slowly dropwise added at room temperature 20.3 gm (0.15 mole) of freshly distilled sulfuryl chloride. After completion of the addition, the solution is stirred for an additional hour, concentrated under reduced pressure (12 mm Hg) at 25°C, and the residue distilled to afford 33 gm (76%), b.p. 49°C (4 mm Hg), of a dark red liquid.

Yield:931-59-9 95%

Reaction Conditions:

with (Dichloroiodo)benzene in dichloromethane at 20; for 0.333333 h;

Steps:

1
Diphenyl disulfide (4.6 mmol, 1 g) was dissolved in 10 mL dichloromethane (DCM).Dichloroiodobenzene (4.6mmol, 1.26g) was added in one portion.Allow to react at room temperature for 20 minutes until the solid material has completely disappeared.The gas phase detection feedstock is completely reacted.The solvent was spin-dried under reduced pressure, and then distilled under reduced pressure to give an orange-red liquid benzene sulphur chloride (I-a) 627 mg.The yield was 95%.
