Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ARYL FRAGMENTS -- AZO-HYDRAZONE -- BENZIMIDAZOLES Аннотация: The synthesis and X-ray diffraction study of 1-benzyl-2-[2-(5- ethyltetrazole-2-yl)-phenoxy]-1H-benzimidazole and 1-benzyl-2-[2-(5- ethyltetrazole-2-yl)-4-nitrophenoxy]-1H-benzimidazole single crystals have been performed. The oxidative splitting of an azo-hydrazone group of 1-(2-hydroxy-(5-nitro)phenyl)-3-ethyl-5-(benzylbenzimidazolyl)formazans, a break in the C2-N1 bond, the interaction of o-hydroxyl group of aryl fragment with oxygen, and the formation of new 2-(phenoxy)benzimidazoles are found to occur in the presence of perchlorate iron(III). \\\\expert2\\nbo\\Crystallography Reports (Кристаллография)\\2013, v.58, N 2, p.271-274.pdf |
