Abstract

The ^13^C NMR spectra of 23 di‐ and tri‐substituted derivatives of esters, thioesters and amides of benzoic acids have been calculated and fully assigned. The A^i^ empirical parameters of the (alkoxy)(dialkoxycar‐bonyl) methylamino, (alkoxy)(alkoxycar‐bonyl)(cyano)methylamino, (alkylamino) (dialkoxycarbonyl) methylamino and (alkylthio) (dialkoxycarbonyl) methylamino groups have been calculated for use in the prediction of the chemical shifts of substituted benzenes.
