Abstract
Reactions of cyclododeca-1,5,9-trienes with Ru3(CO)12 lead to dehydrogenation and isomerisation with the formation of four cluster complexes: in the major product, HRu3(CO)9(C12H15), the monocyclic ligand is attached to the cluster by an unusual allylic bonding arrangement involving only three carbon atoms.
