## Abstract The carbon‐13 spectra of some __para__ and __meta__ substituted phenylferrocenes have been analysed. The substituent‐caused shifts are discussed and compared with similarly substituted biphenyls. Correlations with Hammett parameters and with the reactivity parameters of Swain and Lupton

The 13C NMR signals for some 4substituted phenacyl bromides were assigned. The experimental chemical shifts of the aromatic ring carbons are in close agreement with those calculated using substituent chemical shifts. Both the car-bony1 and the a-methylene carbons exhibit upfield shifts compared with

## Abstract Carbon‐13 NMR chemical shifts and carbon‐proton coupling constants for nine 4‐substituted and six 5‐substituted pyrimidines are reported. The carbon chemical shifts are correlated with π‐electron densities. Carbon‐proton coupling constants fail to correlate with substituent electronegat
