Palladium and Nickel Catalyzed Suzuki Cross-Coupling with Alkyl Fluorides

Abstract

Suzuki cross-coupling of benzylic and unactivated aliphatic fluorides with aryl- and alkenylboronic acids has been achieved via mechanistically distinct Pd and Ni catalyzed pathways that outperform competing protodeboronation, β-hydride elimination, and homocoupling processes. The utility is demonstrated with more than 20 examples including heterocyclic structures, 1,1-disubstituted and trans -1,2-disubstituted alkenes, and by the incorporation of acetonitrile into functionalized (hetero)arenes.
