Reaction Conditions:

with indium(III) oxide;ammonia;water;sulfur in ethanol at 60;Green chemistry;

Steps:

Synthesis of disulfide, 2a-2v; general procedure
General procedure: A mixture of alkyl/aryl halide, 1 (1.2 mmol), ammonium hydroxide (1 mmol) and nanosulfur powder (3 mmol, 96 mg) was stirred in 5mL of solvent (ethanol/water (2:1)) at 60 °C. Under this stirring condition indium oxide nanoparticles (3 mol-%) were added to it and the reaction was stirred for a period of 10 min to 1 h at 60 °C. After completion of the reaction as indicated by thin layer chromatography (TLC), the reaction mixture was cooled to room temperature and a 2:1 mixture of ethyl acetate/water (15 mL) was added and indium oxide was removed by centrifuge. The combined organic extracts were dried with anhydrous sodium sulfate and concentrated to give desired product in high purity.
