In this paper, four functional substituted derivatives of cyclopalladated ferrocenylketimines 1~4, which were as mimetics of metal-dependent esterases for catalyzing the hydrolysis of thiophosphoric acid esters pesticides, were synthesized and characterized. All the four cyclopalladated complexes can efficiently catalyze the degradation of thiophosphoric acid pesticides, such as methyl parathion. The Pd catalyst with coordinated oxime is more active and exhibits an increased selectivity towards sulfur containing pesticides.
