• alpha-Arylchalcogenation
• C(sp3)-H bond functionalization

Direct alpha-arylchalcogenation of acetone with diaryl dichalcogenides has been achieved by using a mixture of TBHP and DTBP oxidants at 120 degrees C without transition-metal catalyst via oxidative C(sp3)-H bond functionalization. The method exhibits good functional group tolerance and products were isolated in moderate to high yields.
