ABSTRACT:
Degradation of phosphate esters, particularly neurotoxins and pesticides, is performed using metallocene derivatives, more particularly molybdocene and tungstocene derivatives. A metallocene derivative is hydrolyzed and then reacted with a phosphate ester. The preferred metallocene derivatives are molybdocene and tungstocene derivatives. The phosphate esters can include, but are not limited to, VX, VE, VG, VM, GB, GD, GA, GF, parathion, paraoxon, triazophos, oxydemeton-methyl, chlorpyrifos, fenitrothion and pirimiphos-methyl, representing both chemical warfare agents as well as pesticides and insecticides.
