WebJun 13, 2016 · The traditional transition metal-catalyzed cross-coupling reaction, although well suited for C(sp2)–C(sp2) cross-coupling, has proven less amenable toward coupling of C(sp3)-hybridized centers, particularly using functional group tolerant reagents and reaction conditions. The development of photoredox/Ni dual catalytic methods for cross … WebAbstract. We describe the first one-pot borylation/Suzuki–Miyaura sp 2 –sp 3 cross-coupling between readily available aryl (pseudo)halides and activated alkyl chlorides. This method streamlines the synthesis of diaryl methanes, α-aryl carbonyls and allyl aryl compounds, substructures that are commonly found in life changing drug molecules.
