Reactivity of α-benzoin oxime with molybdenum(VI)

Article abstract of DOI:10.1080/00945710009351885

In this work, we have presented various aspects of the reactivity of α-benzoin oxime with molybdenum(VI) based on the pH of the aqueous metal ion solution and the ligand/metal ratio. The reactivity of an ethanolic solution of α-benzoin oxime with an aqueous solution of molybdenum in the oxidation state VI was investigated at two pH values (1 and 2.5) and for different values of the ligand/metal ratio. Depending on the experimental conditions, the reaction of α-benzoin oxime (H₂L¹) (C₆H₅(CHOH)-(C=NOH)C₆H₅) with molybdenum(VI) leads to the formation of various complexes: (1) A white monomeric coordination complex of the formula [MoO₂(HL¹)₂].H₂O. (2) A white dimeric coordination complex of the formula Mo₂O₅(HL²)₂(L²) ₂].H₂O in which L² is the deprotonated oxidized form of α-benzoin oxime, C₆H₅(C=O)(C=NO)C₆H₅. (3) A white dimeric coordination complex of the formula [Mo₂O₅(L²)₂(HL³) ₂] in which HL³ is the hydrolyzed form of α-benzoin oxime, C₆H₅(C=O)(CHOH)C₆H₅.
