Н-хелати ацетилоксамідів

Abstract

For the first time was allowed to ascertain, that reaction N-substituted oxamides with acetyl bromide in the icy acetic acid at 75-80 °С, with the control of the heating time (chromatography) lead to give а new group of substance, the name of witch we propose - H­chelates N-substituted-N'-acyloxamides. Were synthesised H-chelates N- substituted-N'­acyloxamides, the structure of which was to bе proved bу elements analysis, bу investiga­tion of the 13C-NMR-, PMR-, infrared spectra.
