SELECTIVE REDUCTION OF DIENES TO MONOENES VIA HYDROGEN TRANSFER REACTION IN THE PRESENCE OF CARBONYL CLUSTERS

Article abstract of DOI:10.1016/0022-328X(85)87118-7

1,5-Cyclooctadiene and 1,5-hexadiene are selectively reduced by hydrogen transfer from i-PrOH using Rh6(CO)16 as procatalyst.The first step of the reaction appears to be the formation of conjugated diene isomers, which are subsequently reduced to monoenes.Carbonyl clusters of Os, Ru and Ir can also be used, but their activities are lower and they predominantly catalyze isomerization.
