摘要
用高分辨核磁共振研究了ω烷基铵基及ω吡啶基芳乙酮α氢在D_2O中的氘交换现象,证实该类酮在酸性与中性条件下产生烯醇化,在弱碱条件下则产生部分烯醇化。
Deuteration of a hydrogen of w - trialkylamminio - acetoarones and w -pyridinioacetoarones in D2O was determined by 1H NMR, 13 C 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.
