Synthesis, characterization, and electrochemical properties of μ-oxalate bridged vanadium(III) and (IV) dimers incorporating the Kläui ligand, CpPORCo (R=Me,Et)

Synthesis And Characterization Of A Series Of Vanadium(iv) Complexes With The Kläui Ligand

“…(CpP OMe Co)and (CpP OEt Co)were successfully used to synthesize the vanadium precursors by our group (84)(85)(86), shown in Scheme 10. These vanadium precursors also have catalytic activities, which will be introduced in next chapter.…”

“…Otherwise, they will quickly oxidize to the vanadium(IV) species. Several vanadium(IV) molecules were synthesized by Anderson and co-workers in our group starting from vanadium(III) precursors (84)(85)(86)88). One example is shown in Scheme 6.…”

“…All these vanadium(IV) complexes have a core with a (O=V)(OPO)2(V=O) ring (64,70,(84)(85)(86)89) and varying groups on the aryl moieties attached to the phosphorus atom. According to Carrano and co-workers, there are four unique dimeric components in a hexanuclear vanadium(IV) cluster, H2O⸦[t-Bupz(μ-C6H5OPO3)VO]6(H2O)2-2CH3CH2OH (70), shown in Our group has synthesized series of vanadium-phosph-(on/in)ate dimers with the methyl Kläui ligand (L OMe )and the ethyl Kläui ligand (L OEt ) -.…”
