用高分辨核磁共振研究了ω-三烷基铵基及ω-吡啶翁基芳乙酮α氢在D2O中的氘交换现象, 证实该类酮在酸性与中性条件下不产生烯醇化, 在弱碱性条件下则产生部分烯醇化。

Deuteration of α hydrogen of ω -trialkylamminio-acetoarones and ω-pyridinioacetoarones in D2O was determined by 1H NMR, 13C NMR, the results of NMR and UV spectra showed that these Arones showed no enolization at PH《8.5, but at PH=8.5-10, showed enolization.

Key words: ELEMENTAL ANALYSIS, ENOLIZATION, NMR SPECTROMETRY, DEUTERIUM, INFRARED SPECTROPHOTOMETRY
