Fig. 1: LMCT-enabled electron relay that utilizes alcohols, including methanol, as sources of reducing equivalents to drive transition metal-mediated cross-electrophile coupling reactions.

A Electron transfer: regulation of back electron transfer to facilitate efficient electron relay. B Ni-Catalyzed cross electrophile couplings (XEC): the critical role of reductants. C LMCT-enabled electron relay: modular utilization of alcohols as tunable reductants to promote Ni-catalyzed XEC.
