Organofunctionalized borotungstate polyoxometalates as tunable photocatalysts for oxidative dimerization of amines.

ABSTRACT: Organofunctionalized borotungstate Keggin polyoxometalates, ( ⁿ Bu₄N)₃H[HBW₁₁O₃₉(P(O)Ph)₂] (PBW₁₁), ( ⁿ Bu₄N)₃H[HBW₁₁O₃₉(As(O)Ph)₂] (AsBW₁₁), and ( ⁿ Bu₄N)₄[HBW₁₁O₃₉(PhSiOSiPh)] (SiBW₁₁), were synthesized and structurally characterized. Cyclic voltammetry showed that the electronic properties of the clusters are dependent on the nature of the appended main group atoms (P, As, or Si). The first reduction potentials were found to shift positively with respect to that of the unmodified parent species ( ⁿ Bu₄N)₅[BW
