To find a fine balance between the M-H and M-H-C ground state structures, hydride migration, to effect C-C bond activation and isomerizations we have studied the low temperature protonation reactions of a series of d8,d9 metal coordinated bicyclo-olefins. We adopted strategies include (a) varying transition metals from 3d, 4d to 5d, (b) changing the electron density in the Cp or arene ring by alkyl substitution, (c) also by changing the nature of bicyclo-olefin ligands namely, bicyclo[2.2.1]-hepta-2,5-diene, bicyclo[2.2.2]octa-2,5-diene, bicyclo[3.2.1]octa-2,6-diene and dicyclopentadiene (dicp) with similar overlap integrals (w) and strain energies.
