    • In the present catalytic system, copper (II) 2-ethylhexanoate could work as the oxygen-activating cocatalyst, and the vanadium could be the active catalyst for the further oxidation of aldehydes into acids, which could be partly confirmed by the fact that copper (II) 2-ethylhexanoate only led to very low conversion of 4-methylbenzaldehyde into 4-methylbenzoic acid in the absence of VO(acac)2 (see Table 2, entry 10, It has to be mentioned that copper salts have been widely reported as oxygen-activating cocatalysts: see (a) Tsuji, J.
