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.

Implication

Demonstrates aerobic α-hydroxylation of β-keto esters with visible light, suggesting a new catalytic approach.

Abstract

A photoactive dinuclear Ir(III)-based amine cage was constructed through dynamic imine assembly followed by reductive fixation. Subsequent post-coordination with Ni(II) ions generated a supramolecular catalytic system that integrates visible-light harvesting...
