Reaction Conditions:

with 1,10-Phenanthroline;potassium carbonate;sulfur in dimethyl sulfoxide at 90; for 12 h;

Steps:

The present invention is achieved in such a way that,To a 25 mL round bottom flask was added o-diiodobenzene (0.5 mmol)Sulfur powder (0.5 mmol),Cuprous iodide (0.05 mmol),1,10-phenanthroline (0.1 mmol),Potassium carbonate (1.0 mmol) andDimethyl sulfoxide (2 mL).The resulting mixture was stirred at 90 ° C for 12 hours.After cooling to room temperature, add 10 mL of water to the system,Then extracted with ethyl acetate (3 x 10 mL) and dried over anhydrous sodium sulfate. After the solvent was distilled off,The resulting residue was purified by silica gel column chromatography in 82% yield.
