THE STRUCTURE AND DYNAMIC BEHAVIOUR IN SOLUTION OF THE TRIHYDRIDODIENERHENIUM COMPLEXES (Ph3P)2(η-1,3-DIENE)ReH3

The structure and fluxionality of the trihydridodiene complexes (Ph3P)2(η-1,3-diene)ReH3 have been studied by NMR spectroscopy (η-1,3-diene = buta-1,3-diene, 2-methylbuta-1,3-diene, 2,3-dimethylbuta-1,3-diene, cyclohexa-1,3-diene, penta-1,3-diene, hexa-1,3-diene and hexa-2,4-diene).Several rearrangement processes have been observed; they are, in order of increasing temperature: (a) ligand interchange; (b) reversible migration of a hydride ligand on to the diene ligand, leading to η-allyl species and, in the case of the cyclohexadiene trihydride, degenerate isomerisation of the cyclohexadiene moiety; and (c), in the case of the pentadiene and hexadiene derivatives, isomerisation of the diene ligand.
