REACTION OF 1,2-DIAMINOIMIDAZOLES WITH ISATINS. DEGREE OF ORDERLINESS OF COMPOUNDS IN A LIQUID-CRYSTAL MATRIX AS A CRITERION OF THEIR STRUCTURE

Article abstract of DOI:10.1007/BF00512967

The reaction of 1,2-diamino-4-arylimidazoles with isatin and N-methylisatin, as a result of which the corresponding imidazo<1',2':2,3>-1,2,4-triazino<6,5-b>indoles were obtained, was studied.The corresponding Schiff base was also isolated in the case of the reaction of 1,2-diamino-4-(p-tert-butylphenylene)imidazole with N-methylisatin.The electronic and IR spectra of the synthesized compounds were studied.The possibility of the use of the degree of orderliness of the synthesized compounds in a liquid-crystal matrix as an additional spectral method in proving the struc tures of the compounds is demonstrated.
