Molecules, Vol. 28, Pages 6139: Tuning Benzylic C−H Functionalization of (Thio)xanthenes with Electrochemistry (Molecules)

Here, we report a tunable electrochemical benzylic C−H functionalization of (thio)xanthenes with terminal alkynes and nitriles in the absence of any catalyst or external chemical oxidant. The benzylic C−H functionalization can be well controlled by varying the electrochemical conditions, affording the specific coupling products via C−C and C−N bond formation.
