Cooperative Ir(III)/Ni(II) Catalysis in a Photoactive Molecular Amine Cage for Visible-Light-Induced Aerobic α -Hydroxylation of β -Keto Esters

Key Points

• The aim is to evaluate the catalytic efficiency of an Ir(III)/Ni(II) system for visible-light-induced processes.
• Constructed a photoactive dinuclear Ir(III)-based amine cage through dynamic imine assembly.
• Post-coordinated with Ni(II) ions to form a supramolecular catalytic system.
• Integrated visible-light harvesting in the catalytic process.
• The catalytic system effectively catalyzed α-hydroxylation of β-keto esters under visible light.
• Showed improved efficiency over previous methods in terms of yield and reaction conditions.
