Abstract: The rates of alkaline hydrolysis of methyl 6-methyl-2-benzoylbenzoate, methyl 6- methyl-2-acetylbenzoate, methyl 6-chloro-2-benzoylbenzoate, methyl 6-chloro-2- acetylbenzoate, and the 6-unsubstituted analogs have been measured. The rates are reported in Table 11. In each case the 6-substituted esters hydrolyze at rates greater than do the corresponding unsubstituted esters. The results are explained by assuming a rate- ...
