15synthesis methods
Bis(4-nitrophenyl) sulfide was synthesized by reacting p-nitrochlorobenzene with potassium xanthate in 95% ethanol refluxed for 48h.
-

Yield:1223-31-0 98%

Reaction Conditions:

with disodium sulphide at 120; for 12 h;Inert atmosphere;

Steps:

1

Under the protection of the nitrogen atmosphere, the 1-chloro-4-nitrobenzene (157 mg, 1mmol), sodium sulfide (39 mg, 0 . 5mmol), N, N-dicarboximide (2 ml) is added to the dry reaction tubes, at 120 °C reaction in oil bath 12h. After cooling the reaction system, by adding 15 ml of water, the aqueous phase with ethyl acetate 30 ml extraction 3 time, combined with the phase, solvent evaporation to dryness under reduced pressure, column chromatography on the obtained yellow solid, in other words, a second-(4-nitrophenyl) thio-ether (132 mg, yield is 98%).
