In the disproportionation of 1,2-dihydronaphthalene catalysed by metal complexes, especially by the Wilkinson catalyst (7), the elimination occurs in two steps.The abstraction of the first hydrogen proceeds with but a small preference for the 2-position - in contrast to dehydrogenations via hydride transfer.The second hydrogen is removed highly stereospecifically from the vicinal cis-position, the acceptor being cis-hydrogenated.Intermolecular H/D-scrambling may occur via allyl hydrido complexes.
