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
