Single-electron transmetalation via photoredox/nickel dual catalysis enables cross-coupling of primary and secondary (bis-catecholato)alkylsilicates with alkenyl halides via transfer of alkyl radicals under very mild reaction conditions. The method works with not only alkenyl bromides and iodides but also previously underexplored alkenyl chlorides.
