Abstract: The E and Z isomers of octa-6-ene-2,4-diynoic acid, were synthesized. Their respective methyl esters were prepared and the structures were determined by spectral data. Long-range CH coupling observed in C-13-NMR fully coupled spectra was particularly elucidating. Semiempirical and ab initio calculations were also carried out in an attempt to evaluate the correlation between atomic charges and the observed chemical shifts.
