Selective Oxygen Atom Transfer to α-pinene, β-pinene, (R)-limonene and camphene by dioxo-Mo(VI)Ln complex {Ln = 2-aminothiazole-4-carboxylic acid} anchored on TiO2 nanotubes (TiO2-NT) using O2 as oxidant and UV light was studied at ambient conditions. The Catalytic system was characterized by FTIR, 1H NMR and 13C, and elemental analysis. Molecular oxygen reoxidizes the (Mo(IV)=O) reduced unit in the darkness, forming an oxo-peroxo-Mo intermediate. The catalyst under UV radiation transfers two oxygen atoms to the olefin. The α-pinene is found to be the most reactive monoterpene.
