Despite recent progress in the catalytic transformation of inert phenol derivatives as alternatives to aryl halides and triflates, attempts at the cross-coupling of inert phenol derivatives with the C?H bonds of arenes have met with limited success. Herein, we report the rhodium-catalyzed cross-coupling of aryl carbamates with arenes bearing a convertible directing group. The key to success is the use of an in situ generated rhodium bis(N-heterocyclic carbene) species as the catalyst, which can promote activation of the inert C(sp2)?O bond in aryl carbamates.

(Chemical Equation Presented) Phenols can be employed as proelectrophiles in operationally simple ruthenium-catalyzed dehydrative direct arylations, proceeding through chemo- and regioselective functionalizations of C-H and C-OH bonds.
