The Wacker oxidation was originally developed as the process of producing acetaldehyde from ethylene using the PdCl2-CuCl2 cocatalytic system. Molecular oxygen can be used as the terminal oxidant.
The reaction can be used to oxidize various terminal alkenes to give the corresponding methyl ketones. DMF is used often as the solvent.
Internal alkenes are usually unreactive, thus terminal alkenes can be oxidized selectively when both are present in the same molecule.

The cooperative catalytic cycle involves the oxidation of the alkene by Pd(II), the oxidation of Pd(0) by Cu(II), and the oxidation of Cu(I) by molecular oxygen.
Terminal alkenes are oxidized more easily than internal alkenes and aldehydes.
