✦ Synopsis

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 †ect of b,c unsaturation being larger than that of c,d unsaturation. The substituent chemical shift (SCS) e †ects of methyl substitution for b,c or d hydrogens were also determined. A linear correlation between the 17O chemical shift for the alcohol (ROH) and the 13C chemical shift for the methyl groups in the corresponding hydrocarbon was (RCH 3 ) obtained, allowing predictions of the 17O chemical shift from corresponding 13C data.

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
