15N?1H and 15N?13C Couplings in 15N-Enriched Dihydroxamic Acids
Original language description
15N-enriched dihydroxamic acids (HONHCO(CH2)nCONHOH, n = 0, 1, and 2) were prepared and their spectra NMR (1H, 13C, 15N) recorded in dimethyl sulfoxide (DMSO) solutions with the aim of determining 15N coupling constants (15N?1H and 15N?13C). The resultssupplement chemical shifts published earlier and yield additional support to the structural conclusions derived from other NMR parameters. Notably, no trace of hydroximic structures could be found in the 15N NMR spectra of these acids. The values of 15N?13C coupling constants backed by theoretical calculations support the assignments made earlier for all of the major conformers and for the minor conformer of succinohydroxamic acid. The enrichment revealed that the minor component ofmalonodihydroxamic acid solution previously considered to be the ZE conformer is in fact the monohydroxamic acid (HOOC?CH2?CO?NH?OH).

Czech description
Byly připraveny 1N-obohacené dihydroxamové kyseliny (HONHCO(CH2)nCONHOH, n = 0, 1, a 2) a změřena jejich NMR (1H, 13C, 15N) spektra v dimethylsulfoxidu. Naměřené interakční konstanty (15N?1H and 15N?13C) souhlasí s teoretickými výpočty a doplňuj9 dosavadní údaje o těchto kyselinách.
