Abstract
A dinuclear Fe(iii) complex (F1) of an imine derivative (L1) derived from 3-ethoxy-2-hydroxy-benzaldehyde and hydrazine, structurally characterised via single crystal X-ray studies, is employed for the catalytic conversion of epoxides to cyclic carbonates utilizing carbon dioxide. In addition, F1 is employed for the selective optical recognition of nano-molar levels of Zn2+ (42.23 nM) via a metal displacement approach. The Job plot reveals interactions between F1 and Zn2+ at a 1 : 3 molar ratio with an association constant of 7.71 × 104 M−1. Studies on the catecholase-like activity of F1 reveal a kcat value of 4.42 × 103 h−1.
A new Fe(iii) complex (F1), structurally characterised using single crystal X-ray studies, was explored for CO2 fixation, Zn2+ recognition and catecholase activity.![]()
