A new Cu(OAc)2-catalyzed oxidative coupling of disulfides with tetrahydrofuran for the synthesis of etherified sulfides has been developed. In the presence of Cu(OAc)2(10% molar fraction) and H2O2(35%,2 equiv),a variety of disulfides(0.5 mmol) were treated with tetrahydrofuran(2 mL) at 120℃ to afford the corresponding etherified sulfides in moderate to high yields. This method employs 35% aqueous H2O2 as the green oxidant,and provides an efficient way for the formation of the C-S bonds.
