  Two step acidic hydrolysis of dialkyl arylphosphonates

  摘要：

  The HCl-catalyzed hydrolysis of dialkyl arylphosphonates monitored by P-31 NMR spectroscopy has revealed two consecutive steps characterized by pseudo first order rate constants k(1) and k(2). A reactivity order for the two steps and for the overall two step hydrolysis has been derived depending on the alkoxy and aryl substituents. Besides the A(Ac)2 mechanism, the A(Al)1 route has been substantiated for the (PrO)-O-i substituent.

  Novel application of simple molybdates: Catalytic hydrolysis of an organophosphate neurotoxin under mild aqueous conditions

  摘要：

  A novel protocol for hydrolyzing phosphonothioate neurotoxins has been developed that uses a readily available, inexpensive and non-toxic molybdate (MoO42). The target organophosphate is O,S-diethylphenyl phosphonothioate (1), a model compound that has served as an analog of the chemical warfare agent VX. Molybdate-mediated hydrolysis of 1 proceeds at room temperature (pH similar to 7.5) and yields a relatively safe phosphonate product through P-S specific scission. This is the first report of utilizing the molybdate, MoO42 , to degrade an organophosphate neurotoxin with turnover. A Delta S-double dagger of 81.5 J/mol.K (-19.5 cal/mol.K) indicates a bimolecular process, and O-18-labeling studies show no oxygen exchange of 1 throughout the hydrolysis by MoO42 (aq). We hypothesize primarily the monomeric molybdate is the active species at pH 7.5 where a S(N)2(P) mechanism takes place. Density functional theory methods suggest the molybdate oxoanion serves as the nucleophile to attack phosphonothioate 1 to form a molybdate-phosphonate anhydride that subsequently hydrolyzes to the starting molybdate and phenylethyl phosphonate.

For each substrate, the leaving group was 4-hydroxyacetophenone while the other two groups attached to the phosphorus core consisted of an asymmetric mixture of methyl, methoxy, ethyl, ethoxy, isopropoxy, phenyl, phenoxy, cyclohexyl, and cyclohexoxy substituents. For the wild-type enzyme, the relative rates of hydrolysis for the two enantiomers ranged from 3 to 5.4 x 10(5)
