- Abstract
Впервые был введен в структуру пиридилзамещенного 4-нитрозопиразола пара- хлорфенильный заместитель циклоконденсацией гидразин гидрата с соответствующими изонитрозо-β- дикарбонильными соединениями. Подробно доказано и изучено строение ранее неизвестных 3(5)-(4-хлорфенил)-5(3)-пиридин-(3(4))-ил‑4-нитрозо‑1Н‑пиразолов и полученных ранее 3(5)-алкил(арил)-5(3)-пиридин-(3(4))-ил‑4-нитрозо‑1Н‑пиразолов современными методами анализа: масс-спектрометрии, ЯМР 1Н- и ЯМР 13С‑спектроскопиями
А para-chlorophenyl substituent was firstly obtained into the structure of pyridyl-substituted 4-nitrosopyrazole by cyclocondensation of hydrazine hydrate with the corresponding isonitroso-β-dicarbonyl compounds. The structure of previously unknown 3(5)-(4-chlorophenyl)-5(3)-pyridine-(3(4))-yl-4-nitroso-1H-pyrazoles and previously obtained 3(5)-alkyl(aryl)-5(3)-pyridine-(3(4))-yl-4-nitroso-1H-pyrazoles is proved and studied in detail by modern methods of analysis: mass spectrometry, 1H- and 13C NMR-spectroscopy
