R 30 Reactions of 2-Arylhydrazono-1,3-dicarbonyl Compounds with Ethylenediamine [Electronic resource] / O. G. Khudina, Ya. V. Burgart, N. V. Murashova, V. I. Saloutin // Russian Journal of Organic Chemistry (Translation of Zhurnal Organicheskoi Khimii). - 2003. - Vol. 39, № 10. - P1421-1428 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: 2-Arylhydrazono-1,3-diketones react with ethylenediamine to give, depending on the substituents, dihydro-1,4-diazepine derivative or N,N'-ethylenebis(1,3-aminovinyl ketones). Treatment of the latter with nickel(II) or copper(II) acetate results in formation of the corresponding metal chelates. Nickel complexes of N,N'-ethylenebis(1,3-aminovinyl ketones) can also be synthesized from 2-arylhydrazono-1,3-diketones and ethylenediamine on a metal template. Reactions of 2-arylhydrazono-3-oxo esters with ethylenediamine yield N,N'-ethylenebis(3-alkyl-2-arylhydrazono-3-oxopropionamides). Ethyl 2-arylhydrazonoacetoacetate reacts with ethylenediamine under mild conditions, affording ethyl 2-p-tolylazo-3-[2-(2-p-tolylhydrazono-1,3-dioxobutylamino)ethylamino]-2-butenoate?? \\\\Expert2\\nbo\\Russian Journal of Organic Chemistry\\2003, 39 (10), 1421.pdf |
