Addition of IN3 to 1-phenylcyclohexene affords the expected Markovnikov product corresponding to the anfi-mechanism. Although further chemical transformations of the product seemed to be in conflict with the proposed structure, extensive 15N NMR experiments finally convinced the authors that the original structure was correct172,193. Iodination of cyclohexene promoted by silver isocyanate was used to prepare the corresponding l rans-i odocy an ate194. 

Swern8 has determined the relative rates of reaction of iodine isocyanate with a variety of unsaturated compounds the results are consistent with an electrophilic reaction. Although it is convenient to use reagent prepared in situ, this reagent is unsatisfactory in the case of acetylenes, which react preferentially to form diiodo compounds.9 In this case it is preferable to use a preformed solution of the reagent, prepared as follows.10 An excess of silver cyanate is treated with iodine in ether, THF, or glyme at — 30° in the dark. Such material reacts at least 10 times faster with olefins than the reagent prepared in situ.
