YieldReaction ConditionsOperation in experiment
With water; dihydrogen peroxide; In ethanol; at 40℃;Kinetics; General procedure: The title reaction was carried out in 1 dram vials with 50mg of the Mo-Y(s) support (0.09 mmole molybdenum); the Mo content was based on elemental analyses of the Mo-Y(s) beads. The ethanol solvent (2.0mL) was added to the Mo-Y(s) followed by addition of 60muL of aqueous 30% H2O2 (0.60 mmole); this suspension was allowed to sit for 20-30min. Kinetic runs commenced with the addition of 0.01 mmole of the phosphorothioate pesticide (2.3muL for parathion, 2.2muL for diazinon and 3.6mg for coumaphos), and all kinetic runs were unstirred unless otherwise specified. At specific time intervals, the solution above the Mo-Y(s) beads/support was transferred from the vial into a 5mm NMR tube without collecting any of the 0.5mm beads. Following a 31P NMR spectrum, this solution was pipetted back to the 1 dram reaction vial containing the Mo-Y(s) beads/support. This process was repeated at various time points for kinetic runs wherein NMR acquisitions were done at the same temperature as the kinetic runs. (0008) For kinetic runs monitored with UV/Vis spectroscopy, the reactions were done in 1.0mL EtOH (40C) with 30muL of aqueous H2O2 (0.30 mmole). After the addition of 0.01 mmole of either parathion or coumaphos, 10muL-aliquots of the EtOH reaction were taken at 5-20min intervals and quenched in 1.5mL 0.10M NaOH. Product formation (i.e. p-nitrophenolate or chlorferon) was recorded at 400nm and 374nm for parathion and coumaphos, respectively. (0009) Rate constants for the oxidative degradation of the phosphorothioate were obtained with both 31P NMR and UV/Vis where the signals fit well to Eq. (2) where C is a constant: (2) Pt=C(1-e-kt) Pt=C(1-e-kt) (0010) In the case of UV/Vis, Pt is the absorbance at either 400nm (parathion) or 374nm (coumaphos) at time t. For NMR kinetic runs, the integrals from all signals (67ppm starting material, 12ppm diethyl phosphite, -4 to -6 ppm oxon and 2ppm triethylphosphate) were combined, and Pt is ratio of the product integral (i.e. either diethyl phosphite or oxon) to the aforementioned total combined signals at time t. All kinetic plots obtained by either 31P NMR or UV/Vis were fitted to Eq. (2) with Solver (Excel) to obtain rate constant k. (0011) Solution (homogeneous) kinetic runs used 56.4mg (0.103 mmole) of 2 in 1.5mL of EtOH with the addition of 15muL (0.15 mmole) of 30% H2O2(aq). Following dissolution of 2 in a 1 dram vial at 60C (?5min), the ethanolic solution of 2 was transferred into a NMR tube, set to the desired temperature and 31P NMR accumulation commenced after addition of 0.01 mmole of the pesticide. All 31P NMR collection (both heterogeneous and homogeneous) used 64 scans with a 3s delay. Prior studies with a similar protocol found that changing the pulse delay did not affect the rate constant [26]. Appearance of products were fitted to Eq. (2) to attain pseudo-first order rate constants for the homogeneous degradation by 2.
