✦ Synopsis
Vinylaziridine 2 undergoes reaction with electrophilic acetylenes and olefins to produce 7-membered azepine derivatTves. With B-nitro-styrene however, a novel rearrangement occurs, presumably via an ene reaction to form lD_, the structure of which is definitively shown by x-ray diffraction. Cis-1,2-Divinylcyclopropanes are known to undergo thermal electrocyclic ring closure to seven n
