Carbon-13 NMR Spectra of Anthraquinone-Derived Dyes

Article abstract of DOI:10.1002/mrc.1260230306

The 13C NMR spectra of six anthraquinone-derived dyes, namely benzanthrone, 1-(methylamino)anthraquinone, 1,4-di-p-toluidinoanthraquinone, 1,4-diamino-2,3-dihydroanthraquinone, 1,4-diaminonanthraquinone and dibenzochrysenedione, have been measured.The chemical shift assignments were achieved by elucidation of the coupling patterns of the fully coupled spectra and by comparison with the chemical shifts of other anthraquinone derivatives and other model compounds.One- and three-bond carbon-hydrogen coupling constants are also reported.
