Recent advances in dual catalysis involving biomimetic conversion strategies that utilize radical ligand transfer (RLT) often rely on large doses of precious metal additives. The role of these additives within the mechanism remains ambiguous, leading to complex reaction conditions, uncertain pathways, and increased costs. These challenges complicate the study of the reaction process and are accompanied by potential safety risks.

Cobalt-nitrogen-carbon (CoNC) materials are regarded as promising low-cost electrocatalysts for the oxygen reduction reaction (ORR). However, their susceptibility to deactivation and poor stability in acidic media limits their practical applications. In this study, we develop cobalt (Co) and manganese (Mn) embedded in nitrogen-doped carbon (CoMnNC) dual-site catalysts by incorporating Mn into CoNC and leverage a synergistic dual-catalysis strategy to optimize both activity and stability.

Herein, we report a mild and operationally simple photoredox/NHC dual catalysis strategy for the α-carboxylation of tertiary amine C(sp)-H bonds using diethyl pyrocarbonate. This method offers a novel approach for synthesizing α-amino acid derivatives. The protocol features a broad substrate scope, accommodating both N-aryl tetrahydroisoquinolines (THIQ) and -methyl aniline and is scalable to gram quantities.

A photochemical Machetti-De Sarlo reaction has been developed for preparing 5-substituted 3-acylisoxazoles from acylnitromethanes and terminal alkynes. This photochemical protocol utilizes an innovative electron donor-acceptor complex, generated from acylnitromethanes, catalytic LiOBu, and 1,1,1,3,3,3-hexafluoro-2-propanol, as a photosensitizer to promote rapid conversion with a broad substrate scope in up to 80% efficiency. A sigmoidal autoinductive kinetic profile is revealed, demonstrating the novel and unique dual catalysis in the first photochemical approach of this reaction.
