Abstract
Isomerisation of pent-1-ene to cis- and trans-pent-2-ene is catalysed at 50 °C and above by solutions in benzene of Fe3(CO)12 and of PdCl2(C6H5CN)2. In both cases, preferential formation of trans-pent-2-ene occurs. Isomerisation of [1,2-2H2]pent-1-ene reveals that each reaction proceeds by the intramolecular transfer of hydrogen and deuterium atoms. The reaction mechanisms involve π-allylic intermediates; for the palladium-catalysed reaction bis-π-allyl complexes may also participate.Keywords
