Notes:
The NMR spectra of the cycloaddition adducts between tetracyanoethylene oxide (TCNEO) and norbornadiene derivatives have been studied. It was shown that there was significant long-range coupling between 7-anti and endo hydrogens in the adducts and that this long-range coupling was solvent dependent. Based on the present study it is concluded that the long-range coupling between endo and anti hydrogens can be as high as 4·1 Hz when an electronegative substituent is attached to the carbon which bears endo hydrogen.
