SYNTHESIS OF ISOBUTYL 2,4-DINITROPHENYL SULPHIDE
- Dissolve 1g (0.005 mol) of 1-chloro-2,4-dinitrobenzene in 5
ml of rectified spirit with warming and add a solution of 0.5 ml (0.005 mol) of
2-methyl-propane-1-thiol in 5 ml of rectified spirit containing 2 ml of 10 per
cent aqueous sodium hydroxide.
- Heat under reflux for 10 minutes and decant the hot solution from any insoluble material into a clean
conical flask.
- Allow the solution to cool, filter and recrystallise the
sulphide twice from methanol.
- The product is obtained as yellow flakes, m.p.
75-76 °C; the yield is 440 mg (35%).
