Wacker process

The Wacker process or the Hoechst-Wacker process (named after the chemical companies of the same name) is an industrial chemical reaction: the aerobic oxidation of ethylene to acetaldehyde in the presence of catalytic, aq.(l) palladium(II) chloride and copper(II) chloride.

The Tsuji-Wacker oxidation refers to a family of reactions inspired by the Wacker process. In Tsuji-Wacker reactions, palladium(II) catalyzes transformation of α-olefins into carbonyl compounds in various solvents.

The development of the Wacker process popularized modern organopalladium chemistry, and Tsuji-Wacker oxidations remain in use today.
