✦ Synopsis


The 13C NMR signals for some 4-substituted phenacyl chlorides and iodides were assigned. The carbonyl carbons exhibit upfield shifts compared with those of the corresponding Csubstituted acetophenones; in the chlorinated derivatives a downfield shift is observed for the cu-methylene carbons, while a reverse effect occurs in the iodinated compounds. The chemical shifts of the aromatic ring carbons are in close agreement with those calculated using substituent chemical shifts.
