Suzuki–Miyaura Csp2–Csp2 Cross-Couplings Employing Nickel(II) Pincer Precatalysts: Mechanistic Investigations

This study investigates the mechanism of Suzuki–Miyaura Csp2–Csp2 cross-couplings facilitated by PCP-type nickel­(II) pincer complexes. By employing a combination of standard experimental and theoretical methods, it is proposed that a nickel­(I)/(III) cycle is involved in this reaction and single-electron pathways likely operate in this transformation.
