Baranov, Yu. Dedkov, A. Musatov] For the prediction of promising directions of the modification of o-arylenediamines as reagents for the nitrite ion, quantum-chemical studies of the corresponding color reactions were performed. It was found that the introduction of C-substituents into aromatic rings insignificantly affects the analytical characteristics of the reactions. An increase in the number of condensed aromatic rings and N-substitution are of interest in searching for a new analytical reagent. The spectrophotometric characteristics of the reaction products of reagents based on 2,3-and 1,8-naphthylenediamines are close to each other, which, possibly, will allow the replacement of 2,3-naphthylenediamine, whose synthesis is extremely complicated, with substantially more available 1,8-naphthylenediamine or its substituted derivatives. The obtained results allowed for the selection of a group of o-arylenediamines interesting as analytical reagents for the nitrite ion, which should be examined practically.
