            General Methods for the Synthesis of 3-Phenyl-sulfanyl-1,2-dihydronaphthalenes ( 9). 
 Under a nitrogen atmosphere, a solution of AIBN (0.3 mmol) and benzenethiol (0.3 mmol) in toluene (10 mL) was dropped very slowly into a solution of 1a (0.3 mmol) in toluene (10 mL) for 2 h at 110 °C and then kept at this temperature for 30 min. Then the solvent was evaporated under vacuum and the residue was subjected to preparative TLC (eluent: PE) to afford the product 9a (70 mg, 74%).Reference Ris Wihthout Link
