Figure 6From: Structures in solid state and solution of dimethoxy curcuminoids: regioselective bromination and chlorinationNMR spectra of solid samples of 2d, 2e and 2f. (a), (b)1H echo MAS NMR spectra (up) and 1H-13C CPMAS NMR spectra (down) for solid sample of 2d and 2e (solid 1, solid 2), respectively. (c) 2D 1H-13C HETCOR NMR spectrum of compound 2f. NMR spectra of solid samples present only enolone region and were recorded on 600 MHz NMR spectrometer.Back to article page
