Abstract

The ^13^C 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‐diaminoanthraquinone 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.

Nineteen derivatives of (1 R)-(+)camphor with deutero, fluoro, bromo, iodo, keto, and hydroxyl functionalities at carbons 3, 5, 8, or 9 have been examined using 13C NMR. The chemical shifts for each carbon of these substituted camphor derivatives have been assigned using broad band decoupling and th
