To provide a process for catalytically oxidizing an olefin or a cycloolefin, for the purpose of forming an α,β-enol, an α,β-olefin ketone, and an epoxide.
This process for catalytically oxidizing the olefin or the cycloolefin comprises solely using a μ-oxy-monometal porphyrin, a bimetal porphyrin, a supported-type μ-oxy-monometal porphyrin or bimetal porphyrin as a catalyst, or using a complex of the μ-oxy-monometal porphyrin or the bimetal porphyrin and a salt or an oxide of a transition metal as a composite catalyst, in a catalyst concentration of 1-50 ppm in the presence of an oxidizing agent, such as air, oxygen, or a mixture of the oxygen and an inert gas, under a reaction pressure of 1-10 atm at a reaction temperature of 20-150°C in a reaction period of 0.5-5 hr. The catalyst is supported on a carrier, so that the catalytic reaction may be conducted homogeneously or heterogeneously. Thus, the process has such advantage that reaction condition is mild, an amount of the catalyst to be applied is small, an efficiency of the catalyst is high, and selectivity is good.
