This method provides a fascinating and green approach for synthesizing a broad range of 2,4-disubstituted quinoline derivatives utilizing simple starting materials and a heterogeneous catalyst in optimum reaction conditions.

All the complexes have been fully characterized by single-crystal X-ray diffraction and mass spectroscopy, which show the CoN<small>₆</small> core structure in all the complexes. The complexes exhibit moderate to good electrocatalytic activity at pH 13.5. During the water oxidation study, an electrocatalytic wave in cyclic voltammetry appears near the Co(IV/III) couple in all four complexes (<strong>1–4</strong>). The electrocatalytic water oxidation occurs at an onset potential of 0.80 V, 0.81 V, 0.72 V, and 0.85 V <em>vs.</em> NHE for <strong>1</strong>, <strong>2</strong>, <strong>3</strong>, and <strong>4</strong>, respectively.

An electron-donating –OMe group in the terpyridine results in the maximum rate, while the electron-withdrawing –F group displays the lowest rate of the water oxidation reaction.
