Deprotonation of cis-(η5-C5H5)(CO)2Re(SiPh3)H by neopentyllithium at -78 deg C in THF gives an anionic species, which is shown by spectroscopic and chemical methods to be ((η5-C5H4(SiPh3))(CO)2ReH)Li.Its formation is explained by initial deprotonation of the cyclopentadienyl ligand, followed by an intramolecular silyl-group migration.Protonation of the anion at room temperature gives trans-(η5-C5H4(SiPh3))(CO)2ReH2.The latter isomerizes to the trans dihydride complex at room temperature (t1/2 12 h).
