✦ Synopsis
The reactions of some vinylcyclopropanes (IVb, IVc and IVd) with Fe(O)5 in refluxing solvent have been shown to involve cyclopropane ring-opening with iron corplexing to give diene n-complexes as major products'. When l,l-dicyclopropylethylene (I) was sirilarly exposed to prolonged action of Fe(C0)5, one of the complexes produced was 3-(l'-prqenyl)-cyclobex-2enonetricarbonyl iron (III), evolved from 1,5-carbonyl insertion on opening of the second cyclopropane ring2.
