Rate coefficients of nucleophilic acyl substitutions, carboxylate carbon 13C NMR chemical shift values and ν (CO) frequencies of several series of aryl and acyl substituted aryl acetates or alkyl benzoates have been investigated. An increasing electron-withdrawal by the acyl or aryl substituents results in higher reaction rates, upfield 13C NMR chemical shifts and higher frequencies of the CO stretching. Good correlations are observed for the log ...
