Abstract: The Suzuki–Miyaura cross-coupling of C(sp3)-hybridised boronic compounds still remains a challenging task, thereby hindering the broad application of alkyl boron substrates in carbon–carbon bond-forming reactions. Herein, we developed an NHC/photoredox dual catalytic cross-coupling of alkyl… read more here.

DOI: 10.1039/d2cc04917a
Abstract: This paper describes iron/photoredox dual-catalyzed acyl nitrene formation and the use of acyl nitrene in constructing various C-O bonds towards phthalides. The developed reaction starts from N-methoxyl-2-alkylbenzamides. Mechanism surveys suggest the reaction involves iron nitrene-based… read more here.

DOI: 10.1039/d2sc06303d
Abstract: A three-component reductive cross-coupling of aryl halides, aldehydes, and alkenes by nickel/photoredox dual catalysis is disclosed. The key to success for this tandem transformation is to identify α-silylamine as a unique organic reductant, which releases… read more here.
