Equimolar reactions of furan (F), 2-methylfuran (MF), and 2,5-dimethylfuran (DMF) with maleic anhydride in acetone-d6 at 60°C were directly followed by NMR spectra. The rates of formation of the two isomers, endo and exo adducts, formed by the Diels

The microfine structure of poly(2-methylenetetrahydrofuran) obtained by various cationic catalysts was studied by NMR spectroscopy. Only a quartet was observed for the backbone methylene protons of the ethyl methyl ketone-insoluble polymer, which was
