N- and S- bonding modes of thiocyanate substituent on catecholase activity as its presence in the coordination sphere of the metal complex can either reduce catecholase activity or otherwise. 4-Methyl-2-((piperidin-1-yl)methyl) phenol - the Mannich base and its synthesized metal complexes were characterized by various spectroscopic techniques including NMR, IR, and UV-Vis spectroscopy. Turnover rates obtained from the Cu(II) and Fe(III) complexes ranged between 6.02 - 22.72 h-1 with the thiocyanate mode in the Fe(III) complex leading to increased catecholase activity.
