Abstract

Two asymmetric polyoxomolybdates Na6{Mo2O5[(Mo2O6)NH3CH2CH2CH2C(O)(PO3)2]2}·16H2O (1) and (NH4)7Na{MoO2[(Mo2O6)NH3CH2CH2CH2C(O)(PO3)2]}4·H2O (2) have been synthesized by the reactions of alendronic acid with molybdate. Structure analysis revealed that the polyoxoanions 1 and 2 can be described as dimeric and tetrameric aggregates of the {MoO3[(Mo2O6)NH3CH2CH2CH2C(O)(PO3)2]} units respectively. Their tetrabutylammonium salts show efficient selective oxidation of benzyl alcohol to benzaldehyde with 72.5% and 81.5% benzyl alcohol conversion, and 87.1% and 82.4% benzaldehyde selectivity, respectively.
