The synthesis of aminophenyl-substituted 2,2′-bipyridine ligands by “1,2,4-triazine” methodology / A. P. Krinochkin, D. S. Kopchuk, M. I. Savchuk [et al.] // AIP Conference Proceedings. - 2021. - Vol. 2388, № 1. - Ст. 030016 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: A convenient synthetic approach to the 2,2’-bipyridines, including those with a condensed cyclopentene fragment, having an aminophenyl substituent at the C5 or C6 positions is reported. The products were obtained via their 1,2,4-triazine analogs with a nitro group, by the subsequent transformation of their 1,2,4-triazine ring into a pyridine one and the reduction of the nitro group to the amino group. |
