[Ru(cod)(cot)] catalyses an unusual dimerization of norbornadiene to give pentacyclo [5.4.21,7.13,6.010,13.012,14]tetradeca-4,8-diene in high yield (85%) with high selectivity, the structure of which is established by X-ray analysis of its brominated derivative, pentacyclo[5.4.21,7.13,6.010,13.012,14]-4,5,8,9-tetrabromotetradecane, to have five five-membered rings as a result of multi-carbon–carbon bond activationn.
