In 2014, Tellis, Primer, and Molander reported a photoredox/nickel dual-catalytic cross-coupling involving organotrifluoroborates. Conventional organoboron cross-coupling relies on a two-electron transmetalation process, whereas transmetalation of C(sp³) organoboron reagents is often relatively ...
C(sp2)- and C(sp)-hybridized coupling reactions are established catalytic approaches. However, multi-step C(sp3)- and C(sp2)-coupling reactions of boronic acids and related derivatives are still limited by ineffective two-electron transmetalation reactions. These conventional protocols exhibit ...
