One-pot gram-scale rapid synthesis of MN complexes with 14-membered ring macrocyclic ligand as a precursor for carbon-based ORR and CORR catalysts.

Herein, CoN, CuN, and NiN complexes with a 14-membered ring hexaazamacrocycle ligand HHAM were synthesised as precursors for ORR and CORR catalysts a one-pot, gram-scale synthesis procedure, which involved microwave heating for only 10 min. Detailed structures of the obtained 14MR-MN complex were revealed by single-crystal X-ray diffraction measurements.
