General procedure
Preparation of (phenethyl)(phenyl)sulfane
In a typical experiment, a mixture of styrene (104 mg,
1 mmol), thiophenol (110 mg, 1 mmol), and Fe3O4 MNPs
(9 mg, 4 mol%) was stirred at room temperature for 3 min.
The course of the reaction was monitored by TLC until the
starting materials had completely disappeared. Then, water
(5 cm3) was added to the reaction mixture, and extracted
with ethyl acetate (3 9 3 cm3). The combined organic layer was dried (MgSO4) and the solvent was evaporated
under vacuum to afford 207 mg (97 %) of pure phenethyl(
phenyl)sulfane as yellow oil. In cases of other
reaction products, further purification was performed by
preparative TLC (silica gel, eluent EtOAc/n-hexane
= 1:10) to obtain pure products.
