The 17O NMR spectra for a series of b,c or c,d unsaturated alcohols are reported. The chemical shift variation due to the introduction of the double bond in the b,c or c,d position was found to be small, with the e β ect of b,c unsaturation being larger than that of c,d unsaturation. The substituent

β¦ Synopsis
Abstract
The use of solution ^17^O NMR spectroscopy in verifying the mechanism of trialkyl phosphite hydrolysis is presented. Trimethyl phosphite was reacted with ^17^Oβlabeled H~2~O at different temperatures and two reactant concentrations, with the reaction being monitored by ^17^O NMR. Kinetic details elucidated from the NMR spectra are also discussed. Copyright Β© 2007 John Wiley & Sons, Ltd.

## Abstract The ^17^O NMR spectra of six different arylmethylenemalonaldehydes were measured for various solvents and temperatures. The ^17^O NMR chemical shifts and line widths of the carbonyl oxygens of the malonaldehyde fragment show a clear variation in the series of monoaryl compounds studied.
The mechanism of ozonolysis was revisited with the use of bridge of the secondary ozonides is carrying the 17 O label. This is contrary to results reported earlier and confirms the 17 O-NMR spectroscopy. In a crossover experiment with 17 Olabelled benzaldehyde and the ozonides of styrene and Criegee
## Abstract ^17^Oβenriched acetic acid (2.5% in ^17^O) was synthesized by hydrolysis of acetic anhydride with ^17^Oβenriched water. The reaction was monitored by ^17^O and ^1^H NMR spectroscopy. Acetic anhydride, ^17^Oβenriched in both the ether and the carbonyl oxygens, was observed as an intermed
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
