Control of Ligand pKa Values Tunes the Electrocatalytic Dihydrogen Evolution Mechanism in a Redox-Active Aluminum(III) Complex

Control of Ligand pKa Values Tunes the Electrocatalytic Dihydrogen Evolution Mechanism in a Redox-Active Aluminum(III) Complex

Redox-active ligands bring electron- and proton-transfer reactions to main-group coordination chemistry. In this Forum Article, we present a bis(pyrazolyl)pyridine ligand platform, iPrPz2P, along with aluminum(III) complexes and describe its redox reactivity. [(iPrPz2P)AlCl2]+ is converted by two-electron reduction and single-ligand protonation to [(iPrHPz2P−)AlCl2]. Electrocatalytic proton reduction mediated by [(iPrPz2P)AlCl2]+ in a tetrahydrofuran solution at −1.26 V versus SCE presumably proceeds through [(iPrHPz2P−)AlCl2] as an intermediate that liberates dihydrogen upon protonation.
