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

✦ Synopsis
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 have been attempted.

The effects of the X and Y substituents on these shifts are discussed, and correlated with substituent constants and with carbon shifts of analogous series of compounds.
## Abstract The ^13^C n.m.r. spectra of four classes of __N__‐aryl sulphur–nitrogen compounds are discussed. The __para__ carbon shieldings of the __N__‐phenyl derivatives reflect the substituents effects of the various nitrogen groups. These show large differences for the four classes of compounds
