ABSTRACT:
A substantially chloride-free palladium oxidation system, comprising a palladium component, a copper component, and a ligand is described. The Wacker system, consisting of palladium and copper chlorides is also improved by the addition of a ligand. The palladium and copper counterion are independently selected from BF.sub.4.sup.--, CF.sub.3 COO.sup.--, CH.sub.3 COO.sup.--, SO.sub.4.sup..dbd., and NO.sub.3.sup.--. The ligand is preferably a nitrile-containing compound.
