Kamienski, Bohdan published the artcileA multinuclear NMR study of the tautomeric equilibria of some indolinones, SDS of cas: 1009-27-4, the main research area is NMR indolinone tautomerism.
1H, 13C and 15N NMR data are reported for three indolinones which, in principle, may exhibit tautomeric equilibrium together with the corresponding NMR results for three model compounds It is found that when taken together the 1H, 13C and 15N NMR results provide a greater insight into both fast and slow exchange equilibrium than would either of these techniques considered alone. The results are indicative of the dependence of equilibrium upon the choice of solvent.
Bulletin of the Polish Academy of Sciences, Chemistry published new progress about NMR (nuclear magnetic resonance). 1009-27-4 belongs to class indole-building-block, name is 2-Ethoxy-1H-indole, and the molecular formula is C10H11NO, SDS of cas: 1009-27-4.
