  日期：1987.2

  The 13 NMR singles for some 4‐substituted phenacylchlorides and iodides were assigned. The carbonyl carbons exhibit upfield shifts compared with those of the corresponding 4‐substituted acetophenones; in the chlorinated derivatives a downfield shift is observed for the α‐methylene carbons, while a reverse effect occurs in the iodinated compounds. The chemical shifts of the aromatic ring carbons are
