✦ Synopsis

The structural assignment of 2-and 4-endo-iodobicydo[3.3.l]non-6-ene-3-endo-~bonitriles was accomplished by evaluation of their COSY spectra. All 'H and =C signals were identified unequivocally. Vicioal 'H-lH coupling constants, NOESY experiments and iodine substitnent effects on the -C chemical shifts show that these molecules prefer the chair conformation.
