Transesterification of Phosphotriester Paraoxon Catalyzed by ZnCl2 Supported on Silica Gel
ZnCl 2 supported on silica gel has shown to be an effective catalyst for transesterification of the organophosphate insecticide, paraoxon, in the presence of 2-phenylethanol. The kinetics of the reaction in acetonitrile was studied. Formation of the product diethyl 2-phenylethyl phosphate was confirmed by 31 P NMR.
