概要
- 論文の詳細を見る
Proton magnetic resonance spectra of several ethyl indole-2-carboxylate derivatives in the presence of a shift reagent, tris (dipivalomethanato)-europium [Eu (DPM)_3], were measured in CDCl_3 and good straight lines were obtained on plotting induced shift vs. concentration of Eu (DPM)_3 for each signal. Application of the McConnell-Robertson equation to interpret pseudocontact shifts of the indole derivatives gave good agreement between measured and predicted shifts. The relationship between substituents of indoles and the position of the co-ordinated Eu atom is discussed.
