The "0 NMR spectra of a number of heterocyclic vinyl ethers were recorded in CDCI, and DMSO-d, solutions. The oxygen chemical shifts reveal substantial differences in the strength of p-n conjugation between the five-and six-membered ring compounds, especially between those with an exocyclic C=C bond

β¦ Synopsis
Natural abundance 17O NMR spectra of some 2-phenylmethylene cyclic ketones are reported. The 17O shifts vary with the ring system, and correlate well with those of the corresponding cyclic ketones. 1997

The 17O NMR spectra of a number of alkyl-and phenyl-substituted divinyl ethers were recorded in CDCl 3 solution. The relationship between chemical shift and the number, nature and position of substituents was explored. The shift values, falling in the range d 100-140 ppm, were found to be remarkably
Intercarbonyl dihedral angles have been estimated by molecular mechanics, which show invariance except in one case. Because of this invariance, contrary to other a-dicarbonyl compounds, a correlation between chemical shifts and dihedral intercarbonyl angles could not be developed. Spectroscopic and
## Abstract The ^17^O NMR spectra of 58 Ξ±,Ξ²βunsaturated (vinyl) ethers were recorded in CDCl~3~ solution. The dependence of the chemical shift on the number and position of alkyl substituents in the vinyl moiety and on the nature and bulkiness of the alkoxy group was explored. The oxygen chemical s
The "0 chemical shifts and one-bond phosphorus-oxygen coupling constants of a series of 1-adamantylphosphoryl derivatives are reported and discussed. It was found that a signi6cant 2p electron transfer towards the phosphoryl oxygen in the phosphonic esters is clearly reflected by the "0 NMR paramete
