Copper + Nickel-in-Charcoal (Cu−Ni/C): A Bimetallic, Heterogeneous Catalyst for Cross-Couplings

A new heterogeneous catalyst composed of copper and nickel oxide particles supported within charcoal has been developed. It catalyzes cross-couplings that traditionally use palladium, nickel, or copper, including Suzuki−Miyaura reactions, Buchwald−Hartwig aminations, vinylalane alkylations, etherifi...

Zusammenfassung:A new heterogeneous catalyst composed of copper and nickel oxide particles supported within charcoal has been developed. It catalyzes cross-couplings that traditionally use palladium, nickel, or copper, including Suzuki−Miyaura reactions, Buchwald−Hartwig aminations, vinylalane alkylations, etherifications of aryl halides, aryl halide reductions, asymmetric conjugate reductions of activated olefins, and azide−alkyne “click” reactions.
