Abstract: A facile synthesis of mono-, 1,1- and 1,2-disubstituted cyclopropanes via visible light-mediated photoredox/nickel dual catalysis is demonstrated. The challenging intramolecular C(sp3)-C(sp3) cross-electrophile coupling of readily available unactivated 1,3-dialkyl electrophiles was performed under mild conditions that… read more here.

DOI: 10.1039/d1cc03668h
Abstract: A photoredox/nickel dual catalyzed reductive hydrobenzylation of alkynes and benzyl chlorides by employing alkyl amines as a stoichiometric reductant is described. This synergistic protocol proceeds via Markovnikov-selective migratory insertion of an alkyne into nickel hydride,… read more here.
