Palladium-nitrile ligand catalyst system and oxidation processes

摘要

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 BF4-, CF3COO-, CH3COO-, SO4=, and NO3-. The ligand is preferably a nitrile-containing compound.
