Abstract
In this report, we use alkyl and aryl mesylates as coupling partners for a C(sp²)-C(sp³) cross-electrophile-coupling reaction. The methodology employed visible-light photoredox/nickel dual catalysis and an organic amine as the terminal reductant. The study involved crucial reaction design and demonstrated the role of mixed ligands in preventing self-coupling and undesired deoxygenation. Operating at mild reaction conditions, the method accommodates large functional groups. Since both the coupling partners could be derived from abundant alcohol, the strategy brings a highly sustainable perspective.
