Karazin popup.description2 Triazolil-2-pyrazolines, imidazo[1,5-a]pyrimidines, 3-phenilquinoxalones, 3-phenil-2-methylidenecarboxy-1,2-quinoxalines, 5,7-diaryl-4,7-tetrazolo[1,5-a]pyrimidines, 2-imino-3-thiazolyl-2-coumarines are the objects of the study. The aim of the research work is to synthesize the new organic compounds of pyrazoline, imidazo- and tetrazolo[1,5-a]pyrimidine and coumarine series and to study their chemical and spectral properties. IR, UV, NMR-spectroscopy, mass-spectrometry, X-ray analysis were used in the investigation. As the result there have been synthesized new derivatives of N-triazolyl-2-pyrazoline, 3-phenacylquinoxalone, imidazo[1,5-a]pyrimidine, dihydrotetrazolo[1,5-a]pyrimidine, N-aryl-3-thiazolylchromenimines. Their structure as well as chemical and spectral properties were studied. Product Description popup.authors popup.nrat_date 2020-04-03 Close
