The structural assignment of 2‐ and 4‐ endo ‐iodobicyclo[3.3.1]non‐6‐ene‐3‐endo‐carbonitriles was accomplished by evaluation of their COSY spectra. All 1 H and 13 C signals were identified unequivocally. Vicinal 1 H‐ 1 H coupling constants. NOESY experiments and iodine substituent effects on the 13 C chemical shifts show that these molecules prefer the chair conformation.
