Abstract
The present invention provides a process for the preparation of a Pd(0)Lcomplex, where L is a ligand and n is 2, 3 or 4, comprising the steps of: (a) reacting a Pd(II) complex in at least one solvent with a base and ligand L; and (b) if required, adding further base, optionally in at least one solvent, to form the Pd(0)Lcomplex; wherein the at least one solvents in steps a and b are independently the same or different, and provided that when n=2, the Pd(II) complex is not bis[tri(ortho-tolyl)phosphine] palladium chloride. The invention also provides novel Pd(0)Land Pd(II) complexes.
