摘要：
A detailed study of the 270 MHz H-1 and 67 MHz C-13 NMR spectra of four series of dimedone adducts and ''anhydrides'' is presented. A valuable (5)J(HH) homoallylic coupling has been identified which has facilitated signal locations utilising 2D HETCOR and COLOC experiments. Some earlier spectral assignments are revised.
