Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): NMR -- TAUTOMERISM -- SYNTHESIS Аннотация: The reaction of bis(polyfluoroalkyl)-containing 1,3,5-triketones with o-phenylenediamine yielded 2-polyfluoroacylmethylene-4-polyfluoroalkyl-1,3- or 1,5-dihydro-1,5-benzodiazepines. The tautomeric equilibrium of the obtained benzodiazepines in CDCl3, CD3CN, DMSO, and DMF solution was studied.?? |
