Abstract The 77 Se, 13 C and 1 H NMR spectra of the products of phenylselenenyl azide and chloride addition to methylenecyclohexane and cyclohexene are presented. Scalar couplings between 77 Se and 1 H/ 13 C allowed the absolute assignment of the regioisomers in the 1 H and 13 C spectra. Low‐temperature 77 Se NMR was used to determine the conformer ratios for 1‐azidomethyl‐ and 1‐chloromethyl‐1‐phenylselenenylcyclohexane anti‐Markovnikov addition products.
