Benzoyl benzoate

This is not a direct benzoylation reaction, but benzyl benzoate may be prepared by the interaction of freshly distilled benzaldehyde with sodium benzylate. It is an exothermic reaction and the temperature of the reaction mixture should be maintained between 50-60°C. The final product is obtained by distillation rmder reduced pressure and the distillate collected at 184-185°C/15 mm pressure. 

5 Procedure. The various steps involved are as stated below  

Note The resulting benzyl benzoate supercools readily, but after solidification does melt within one degree of the highest recorded value (19.4°C) and, therefore, does not require any refractionation ordinarily. 

7 Theoretical Yield/Practical Yield. The theoretical 3neld may be calculated from the equation under theory (Section 4.2.5.3) as stated below

Perhaps the most informative studies (Anvia and Bowden, 1990) of leaving groups are of the alkaline hydrolysis of 3-substituted phenyl 2-acetyl- and 2-benzoyl-benzoates [20], The Hammett reaction constants p are ca. 0.50 and 1.48 for the 2-acetyl and 2-benzoyl esters respectively, as. shown in Table 2. These were compared with various limiting models in a similar manner to the effective charge model (Williams, 1984,1992). This comparison indicates that all simple phenyl esters of the latter types hydrolyse by a mechanism...

Several acids have been esterified by reaction with propene, " isobutylene, and ttimethylethylene. " The reaction is reversible and catalyzed by sulfuric acid or boron trifluoride. The optimum conditions for maximum conversion are low reaction temperature, large quantity of catalyst, and anhydrous conditions. " By this method, the keto ester, t-butyl o-benzoyl benzoate, " and the halo esters, f-butyl and isopropyl trichloroacetates,have been prepared.
