Carbon-13 nmr has been found to be an effective spectroscopic method for measuring the ratio of isomeric monoethyl esters resulting from the esterification of 4-nitrophthalic acid, the alcoholysis of 4-nitrophthalic anhydride, and the catalytic reduction of monoethyl 4-nitrophthalates.Precise values of the (13)C chemical shifts for 1-ethyl and 2-ethyl 4-nitrophthalate and the corresponding 4-aminophthalates were determined; the shielding parameters are explained in terms of known structural effects.Details of the esterification, alcoholysis, reduction reactions, and the isolation of 1-ethyl 4-nitrophthalate are described.
