Benzoic methyl ester

Ethyl Acetoacetate. -The e. planation of the manner in which this substance is produced has been given in the account of the preparation. The result was anived at, not by the iscila-tion of the intermediate compound formed by the union of ethyl acetate with sodium ethylate, but by analogy with the behaviour of benzoic methyl ester with sodium benzylate, which gave the same additive product as that obtained by combining benzoic benzyl ester with sodium methylate, showing that such combinations could occur,... 

The above intermediate compound lias not boon isolated, bnt by the interaction of benzoic methyl-ester and sodium bemaylate an analogous compound has been produced and separated,... 

Benzoic Esters.—Tafel and Friedrichs,2 by conducting the electrolysis in alcoholic-aqueous sulpnuric acid at lead or mercury cathodes, obtained methyl benzyl ether and the ethyl benzyl ether from benzoic methyl and benzoic ethyl esters respectively. Mettler,3 by a similar arrangement, obtained chiefly benzyl alcohol and some benzyl methyl ether from benzoic methyl ester. 

The following compounds when heated with hydrochloric acid yield mercuric chloride and an organic acid The anhydride of o-hydroxy-mercuri benzoic acid and the anhydride of a-hydroxy mercuri- -hydroxy-j3-phenyipropionic acid, whilst o-chloromercuri benzoic methyl ester is decomposed by halogen acids, and cold dilute hydrochloric acid eliminates the acetoxymercuri group attached to the nitrogen in N-isodiacetoxymercuri anthranilic methyl ester.

Example 4.3. The p value for alkaline saponification of methyl esters of substituted benzoic acids is 2.38, and the rate constant for saponification of methyl benzoate under the conditions of interest is 2 x 10 s . Calculate the rate constant for the hydrolysis... 

Methyl Anthranilate.—This ester is one of extreme importance, and to it is largely due the possibility of manufacturing artificial neroli oils. It was discovered as a constituent of neroli oil in 1895 by Walbaum, and has since been identified in numerous other flower oils, such as tuberose, ylang-ylang, jasmin, and gardenia. Its value in synthetic perfumery is therefore obvious. Its constitution is that of a methyl ester or orthp-amido-benzoic acid, of the formula here shown —... 

It is, therefore, the methyl ester of 2-methylamino-3-methoxj benzoic acid.

Optically active (+)- and (—)-p-(/-propylmethylphenylstannyl) benzoic acids (56) and their methyl esters (57) were similarly prepared by Lequan four years later 38) (see Table 3). They are characterized by very low optical rotations. Furthermore, the diastereomeric brucine salts via which the acids were resolved, are characterized by almost identical NMR spectra that cannot be used to follow their separation so that no precise information is available about the optical purity of (56) and (57). 

The coordination modes found in Ni11 complexes with 2-(diphenylphosphino)nicotinic acid and its methyl ester and 2-(diphenylphosphino)benzoic acid and its methyl ester are surprising.696 The complex with the benzoic acid derivative shows the expected P,0 coordination with a six-membered chelate ring (252), while the nicotinic acid analogue forms a four-membered chelate ring with P,N binding (251). 

Use of a catalytic cocaine antibody may bypass this potential downfall of the active immunization approach. The enzymatically active catalytic cocaine antibody cleaves cocaine into two inactive metabolites ecognine methyl ester and benzoic acid. The two metabolites are released from the catalytic antibody rendering the antibody free to degrade more cocaine. Because the...
