Alkene cleavage large scale oxidations

The well-known Wacker oxidation of terminal alkenes to methylketones has been used for many years on a large scale. It requires a catalytic amount of Pd(II) together with stoichiometric CuCl2 under aerobic conditions. But it is hmited by palladiiun decomposition and chlorinated byproducts. Therefore, a lot of research has been devoted to modifying the reaction, but most of the time copper cocatalysts were necessary. Another problem is the often observed cleavage of the double bond and the production of aldehydes. [Pg.192]
