<p>An economical process is described for the oxidation of allylacetone to 2,5-hexanedione using palladium chloride catalyst in the presence of copper chloride and oxygen, the reaction being carried out in a heterogeneous solvent system which is a mixture of water and a high-boiling hydrocarbon solvent, specific such solvents being either trichlorobenzene, hexachlorobutadiene, triethylbenzene, diphenyl ether or .alpha.-chloronaphthalene. High yields of product are obtained in minimum reaction times and with minimal losses of the expensive palladium catalyst.</p> |
