Polybenzimidazole palladium chloride complex

Sherrington and coworkers have used polybenzimidazoles and polymides to complex metal ion catalysts and thus avoid or minimize losses of the metal ions, some of which are expensive. The first has been used to complex palladium(II) for the Wacker reaction (5.47) of 1-octene and 1-decene to ketones.204 (The other reagents for this reaction are copper(II) chloride and oxygen.)...
