| 摘 要： | Thiophosphoric acid esters pesticides such as parathion, methyl parathion, with an annual world production of hundred thousands of tons, are powerful pollution sources and their remains in the environment is a recognized ecological threat1. Creation of 揼reen拻 catalytic processes for degradation of thiophosphoric acid esters is therefore an urgent task of contemporary chemical technology and biotechnology. Significant progress has been made by the use of organophosphate hydrolases (OPH), a…

| Abstract: | In this paper, four functional substituted derivatives of cyclopalladated ferrocenyl- ketimines 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. |
