, p. 271 - 275 (1990)
The 13C NMR spectra of 23 di- and tri-substituted derivatives of esters, thioesters and amides of benzoic acids have been calculated and fully assigned.The Ai empirical parameters of the (alkoxy)(dialkoxycarbonyl)methylamino, (alkoxy)(alkoxycarbonyl)(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.

The rearrangement of 2,4-dinitro- and 2,4,6-trinitrobenzylidenemalonates in reaction with thiols, both in or without the presence of alcohols or amines has been found to afford various 2-amino-4-nitro- and 2-amino-4,6-dinitrobenzoic acid derivatives, i.e.
