The mechanism of the copper-catalyzed regioselective ortho C–H cyanation of vinylarenes has been investigated using density functional theory calculations. This C–H cyanation is composed of two discrete catalytic cycles (the copper-catalyzed electrophilic cyanative dearomatization and the subsequent base-catalyzed hydrogen transposition) that furnish the ortho C–H cyanated arenes. The electrophilic cyanation step features a unique six-membered transition state, leading to the formation of the dearomatized intermediate with a high level of site selectivity. Such dearomatization significantly increases the reactivity of the C–H bond, thereby enabling the base-assisted C–H activation in the following steps.
