✦ Synopsis

Abstract

The ^17^O NMR data of thio analogues of chromanones, chromones, flavanones and flavanones are compared with those of corresponding oxygen analogues. Substituent effects are discussed in terms of steric and electronic interactions and also the conformational behaviour of some substituents and the hetero ring.

## Abstract The ^17^O chemical shifts of nine sulphinylimines and isocyanates are reported and discussed in terms of electronic and mesomeric effects. Unusually large values were found for the sulphinylimines. The differences in acyl fluorides compared with acyl chlorides are rationalized on the ba

The 54.2 MHz I7O NMR spectra of a series of naturally occurring coumarins and furocoumarins and those of a number of related model compounds are described. The ''0 chemical shifts of the furocoumarins can be predicted by the evaluation of the data of substructures in model compounds. syn-Periplanar
