Formation of Low-Valence Palladium Species in the Course of Oxidation of Alcohols with Palladium(II) Tetraaqua Complex

摘要

The formation of low-valence palladium species Pd_n~(2+) (n >= 2) in the course of oxidation of aliphatic C_1-C_4 alcohols with oxygen in the presence of palladium(II) tetraaqua complex in aqueous solution was proved UV-spectrophotometrically by the absorption band with a maximum at 312 or 316 nm depending on particular alcohol.
