Mechanistische Untersuchungen zur Isomerisierung von Allylalkohol zu Propionaldehyd mit dem Clusteranion - als Katalysator

The trinuclear cluster anion ^- catalyses the isomerisation of allylic alcohol to propionaldehyde at room temperature.The reactivity of other allylic systems is markedly dependent upon the substituents: while 2-butene-1-ol and 1-pentene-3-ol are also isomerised, the homologues 2-methyl-2-propene-1-ol, 3-phenyl-2-propene-1-ol remain unchanged.The catalytic mechanism is discussed on the basis of the kinetic data and of isotope labelling studies: the reaction probably proceeds through the intermediacy of intact Ru3 clusters.
