Abstract: In aqueous solutions D-erythrose, D-threose, 5-deoxy-L-ribose, and 5-deoxy-L-arabinose form complexes with ammonium molybdate in the form of their α-anomers. 13C NMR 1H NMR, and optical rotation data pointed out that molybdate complexes of D-erythrose and 5-deoxy-L-ribose involve interaction with the hydroxyl groups at C-1, C-2, and C-3, while those of D-threose and 5-deoxy-L-arabinose involve interaction with C-1  and C-3 hydroxyl groups. 5-O-α-D-Galactopyranosyl-D-arabinose does not complex with molybdate ions and is not epimerized under catalytic action of molybdate ions.
