The effect of the substituent in the benzoyl group on the relative rate and activation parameters of transesterification of substituted 4-nitrophenyl benzoates with 4-chlorophenol in dimethylformamide in the presence of potassium carbonate was studied by the competing reaction technique. The whole series of benzoates showed the enthalpy-entropy compensation effect. 4-Nitrophenyl benzoates having electronacceptor substituents give rise to isokinetic relationship with an isokinetic temperature β of 382 K. The mechanism of the transesterification process is discussed. Pleiades Publishing, Inc., 2006.

The response of the carbonyl-carbon chemical shift to the substituent effect in aryl 4-X-benzoates 3-6 has been studied in CDCl3.The comparison with relevant data for methyl benzoates 1 and acetophenones 2 shows, along the 3-to-6 sequence, a gradual shift
