DETERMINATION OF 3-BOND H-1, H-1 COUPLING-CONSTANTS BETWEEN THE OLEFINIC PROTONS IN CYCLOALKENES BY MEANS OF H-1 CW OFF-RESONANCE C-13 NMR-SPECTROSCOPY
R. Radeglia et al., DETERMINATION OF 3-BOND H-1, H-1 COUPLING-CONSTANTS BETWEEN THE OLEFINIC PROTONS IN CYCLOALKENES BY MEANS OF H-1 CW OFF-RESONANCE C-13 NMR-SPECTROSCOPY, Magnetic resonance in chemistry, 31(7), 1993, pp. 639-641
The H-1 CW off-resonance decoupled C-13 NMR spectra of (E)- and (Z)-cy
cloalkenes (C5-C-12) were measured. The higher order C-13 NMR multiple
ts obtained for the unsaturated carbons allow the determination of the
vicinal H-1,H-1 coupling constant between the vinylic protons and thu
s the assignment of the configuration of the -CH2CH=CHCH2- fragment.
