The liquid-phase oxidation of p-methoxytoluene to p-anisaldehyde in the presence of Co based catalysts has been studied.With Co(OAc)2 alone in acetic acid as a solvent, only a trace amount of p-anisaldehyde could be obtained; however, upon the addition of a second metal salt (e.g., Mn(OAc)2 or Ce(OAc)3) a considerable improvement in the yield (up to 60percent) was observed.The synergism of Co and the second component as well as the optimization of the reaction conditions were investigated.Co(OAc)2-Ce(OAc)3-Cr(OAc)3 (3:1:2) was finally found to be the most effective catalytic system, which gave a 76percent yield op p-anisaldehyde under 3 atm O2 at 110 deg C for 3 h.
