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