Thus good yields (> 60 per cent) are obtained with aniline and methyl, ethyl, n-propyl and n-butyl phosphates with a- and P-naphthylamine and methyl or ethyl phosphate nuclear substituted anilines and methyl or ethyl phosphate. 

Diethylaniline. Use 28 g. of pure aniline and 36 g. (34 ml.) of purified ethyl phosphate, and proceed exactly as described for dimethylaniline. The reaction is not so vigorous initially. Separation into two layers occurs after 30 to 90 minutes. The yield of diethylaniline, b.p. 215-216°, is 41-5 g.

Caglioti et al.201 suggested a mechanism for the action of hexachlorocydotriphos-photriazene in the polyesterification of carboxylic acids with phenols. Higashi291 catalyzed the reaction of various aromatic acids and alcohols by poly(ethyl phosphate). Both Caglioti201 and Higashi291 studied the influence of tertiary amines on the reactivity. 

Of the three organic phosphorus insecticides—hexaethyl tetraphosphate, tetraethyl pyrophosphate, and parathion—the first two have been shown to be mixtures (36) that contain tetraethyl pyrophosphate as the principal active ingredient. Several methods have been proposed for the determination of this compound in the commercial products (25, 35). All are based on the separation of the tetraethyl pyrophosphate from the related ethyl phosphates, followed by its hydrolysis to diethyl orthophosphoric acid and titration with standard alkali. Both hexaethyl tetraphosphate and tetraethyl pyrophosphate are soluble in water and are rapidly hydrolyzed to monoethyl and diethyl orthophosphoric acid. This rapid hydrolysis to nontoxic products greatly limits the duration of the in- secticidal effectiveness of tetraethyl pyrophosphate, but it also eliminates the danger of toxic residues on the crops treated.

The product was undoubtedly a mixture and contained some T.E.P.P. It may be noted that we showed that one of the primary actions2 of triethyl phosphate on phosphorus oxychloride is to give EtO P0C12 and (EtO)2POCl, hence a complex mixture is likely to result from the further splitting out of ethyl chloride between the primary product and the original ethyl phosphate. 

The above enzymes are not the only ones able to cleave phosphoric acid esters. Indeed, the cleavage of some organophosphates can be catalyzed by monooxygenases, as illustrated below. Furthermore, glutathione S-transfe-rases can also act on some methyl and ethyl phosphates [73], but these reactions will not be covered here.

Aminoacyl adenylates (296), which are formed from protein amino acids and ATP, act as acylating agents towards t-RNAs, acylating their terminal 3 -hydroxy groups. These charged tRNAs are then used in protein synthesis. Little is known about the reactivity of aminoacyl adenylates (296), and studies are now reported of a model compound, alanyl ethyl phosphate (297). As expected, hydrolysis in both acid and base involves attack at the C=0 group of (297) with departure of ethyl phosphate. Metal ions (Cu +, Zn +) were found to act as catalysts of the hydrolysis.

Parathion degraded on both glass surfaces and on bean plant leaves. Metabolites reported were paraoxon, 4-nitrophenol, and a compound tentatively identified as 5-ethyl parathion (El-Refai and Hopkins, 1966). Upon exposure to high intensity UV light, parathion was altered to the following photoproducts paraoxon, 0,5-diethyl 0-4-nitrophenyl phosphorothioate, 0,0-diethyl 5-4-nitrophenyl phosphorothioate, 0,0-bis(4-nitrophenyl) 0-ethyl phosphorothioate, 0,0-bis(4-nitrophenyl) 0-ethyl phosphate, 0,0-diethyl 0-phenyl phosphorothioate, and 0,0-diethyl 0-phenyl phosphate (Joiner et al., 1971).

In accordance with the two ester mechanism, the first step in the polymerization of ethylene in the presence of phosphoric acid is the formation of an ethyl phosphate (Ipatieff and Pines, 70).
