Cyclometalated Half-Sandwich Iridium(III) Complexes: Synthesis, Structure, and Diverse Catalytic Activity in Imine Synthesis Using Air as the Oxidant

Four air-stable cyclometalated half-sandwich iridium complexes 1–4 with C,N-donor Schiff base ligands were prepared through C–H activation in moderate-to-good yields. These complexes have been well...
