In the way of literature precedent, ( ) and ( ) are corroborated by the demonstrated experimental ability of palladium and platinum dioxygen compounds to form peroxycarbonte ligands from CO 2 exposure. Additionally, the tendency of aqueous O 2 2to form CO 4 2from atmospheric carbon dioxide is known to be been an issue for lithium ion battery rechargeability. Once generated, the potential of peroxycarbonates to serve as oxygen atom transfer agents has been demonstrated extensively by Aresta and co-workers for external phosphines and olefins. Moreover, ozone intermediates not dissimilar to (3) have been predicted in an olefin epoxidation mechanism. It is also worth mentioning that the alkali-balanced Vanadium products, x -→ CO 2 transferred charge, as measured through the sum of the partial charges on the CO 2 unit in [M(O 2 ) 3 (κ 1 -CO 4 )] x -, with increased exergonicity of int1 formation can be seen (Table ). It therefore stands to reason that the initial charge on the oxygen atoms in [M(O 2 ) 4 ] x - should be related to the tendency to form [M(O 2 ) 3 (κ 1 -CO 4 )] x -. Despite this relationship, only a weak linear correlation exists between q O in [M(O 2 ) 4 ] x -and the Free energy of formation of int1 (R 2 = 0.52, Figure ). Clearly more factors are at play than just the charges of the oxygen atoms in the precursor complex.
