1-Nitro-4-benzothiazolylsulfanyl-and -sulfonyldienes were synthesized. The former were obtained by thiylation of 1,4-dinitrodienes, and the latter were prepared from the former by oxidation with hydrogen peroxide. The spatial structure of compounds obtained was considered.

Electrodes modified with poly(arylene phthalide ketones) were developed for the voltammetric determination of isomers of aromatic nitro compounds. A polynomial algorithm for processing analytical signals from a sensor array was tested in the analysis of ternary mixtures. It is shown that the sensor array offers promise for analyzing multicomponent mixtures in the case when analytical signals overlap.
