This study mapped the structural features which control the regiochemistry of hydride abstraction by Ph//3C** plus PF//6** minus from alkyls eta -C//5H//5)Re(NO)(PPh//3)(R). Accurate predictions can now be made regarding the reactivity of yet unsynthesized rhenium alkyls. Detailed transition-state models for alpha - and beta -hydride abstraction have been proposed. This study has also provided additional examples of the ability of ( eta -C//5H//5)Re(NO)(PPh//3) systems to participate in stereospecific and/or highly stereoselective reactions. The rhenium chirality is efficiently transferred to new, ligand-based centers or elements of chirality.
