Abstract
Carbon‐13 chemical shifts of 22 derivatives of dibenzobarrelene, anthraquinone and anthracene are reported, each of which includes a symmetrical ortho‐benzene moiety. The assignment of the chemical shifts of the aromatic carbons of these derivatives was achieved by correlation with the corresponding ^13^C chemical shifts of ortho‐disubstituted benzenes.

Some derivatives of benzoxazolinone are studied by 'H and 13CNMR spectroscopy. 6-Crotonoyl (or cinnamoyl)-3methylbenzoxazolinones exist in the (8configuration and prefer the syn-planar conformation. 2,3-Dihydro-2,5-and 2,3dihydro -2,7 -dioxo -3-methylcyclopenta -[flbenzoxazoles are easily distinguis
## Abstract Assignment of all ^13^C chemical shifts of perezone (1) and some derivatives was possible using time averaged 25·15 MHz spectra with the aid of proton noise modulated and CW decoupling. Rapid interconversion of tautomeric forms of 2,5‐dihydroxy‐1,4‐benzoquinones is deduced from the ^13^
The 13C NMR spectral data for 18 dihydropyrimidinediones and their 2-thio analogues are presented. The influence of substituents on the shielding of neighbouring atoms was analysed and the resonances were unambiguously assigned. 13C NMR spectroscopy was shown to be useful for structural determinatio
