Аннотация
A general and simple procedure for the synthesis of 3-nitroformazan using arenediazonium tosylates was developed. This convenient procedure can be applied for the preparation of 3-nitroformazans containing electron-donating or electron-withdrawing groups. First the anomaly 1,5-bis(4-methoxyphenyl)-3-nitroformazan was synthesized as the mixture of TSSC (trans-syn, s-cis) and previously unknown for 3-nitroformazans TASC (transanti, s-cis) isomers. The structure and spectral characteristics of TASC isomer were explained using quantumchemical calculation with TDDFT/B3LYP/6-31++G(d,p) level of theory.
