study of the bismuth-catalyzed transfer hydrogenation of azoarenes. With the protocol using p-trifluoromethylphenol and pinacolborane, we identified the role of protic and hydridic hydrogens through kinetic analysis and reactivity studies. The possibility of Bi-ligand cooperativity was assessed through isotope labeling experiments. This work validates the notion of Bi(I)/Bi(III) redox cycling.
