The reaction of alpha-iodo-beta-nitrostilbene with morpholine or piperidine yields alpha-nitro-beta-morpholino- or alpha-nitro-beta-piperidinostilbene. The reaction is regioselective and stereospecific: only the iodine, and not the nitro group, is substituted, the product obtained has a cis structure regardless of whether the initial substrate had a cis- or a transconfiguration. The prereaction stage probably includes the formation of a charge-transfer complex between substrate and reagent.
