The cooperative action of Ru and Cu catalysts enables direct polynuclear C–H and N–H activation for the dehydrogenative N-carbazolation of carbazoles, selectively at the C1 position. Initial mechanistic experiments are presented and discussed.

The mechanism of a trinuclearcooperative dehydrogenative C−N bond‐forming reaction is investigated in this work, which avoids the use of chelate‐assisting directing groups. Two new highly efficient Ru/Cu co‐catalyzed systems were identified, allowing orders of magnitude greater TOFs than the previous state of the art. In‐depth kinetic studies were performed in combination with advanced DFT calculations
