    • The large size of Re and P in these rings is expected to favor smaller ring sizes than organic counterparts, which suggests that seven- and eight-membered rings are more destablized than organic systems.

    • One possibility for this kinetic discrepancy could be tighter ion pairing for the smaller anions, which may aid in the transfer of hydride between two cationic species.

    • note
    • 3 generally resulted in much more hydride formation and were thus avoided. These reactions were sometimes accompanied by intense color changes consistent with reduction processes, which would labilize the CO ligands and lead to reactivity at Re itself.
