C−P Bond Formation by Nickel or Cobalt Catalyzed Coupling Reactions

Chemistry - An Asian Journal, Journal Year: 2025, Volume and Issue: unknown

Published: March 12, 2025

Abstract This review discloses nickel‐ and cobalt‐catalyzed coupling reactions that allow C−P bond formation. Activation of C−halide bonds to form phosphonium, pentavalent phosphorus, or trivalent phosphorous compounds has been reported with both metals. However, the conversion C−O ((activated) ethers, carbonates, acetates) into ones only described Ni. Similarly, there are more examples C−Y (Y=C, S, N, B) activations catalyzed by Ni than Co. Nevertheless, cross‐dehydrogenative reaction between a P−H reagent C−H often cobalt nickel. In addition, for metals, electrolytic photocatalytic processes have shown produce variety containing molecules. aims provide an overview potential metals formation highlight remaining challenges.
