Abstract

17O NMR data for some 3-arylidenechromanones and -flavanones are discussed in terms of mesomeric and steric substituent interactions. The transmission of long-range substituent effects was studied. 17O NMR chemical shifts were correlated with Hammett σp+ values for 4′-substituted derivatives.
