Dandarova, Miloslava,Vegh, Daniel
, p. 1141 - 1144 (1992)
1H and 13C NMR spectra of 22 2-substituted 4,5-dimethylfurans are reported.The J(C,H) values were used for signal assignments and for the identification of geometrical isomers of some derivatives. KEY WORDS: 2-Substituted 4,5-dimethylfurans, 1H and 13C NMR spectra
