1-5% mole palladium species has commonly been used in homogenous system with palladium being generated by [Pd.sup.2+] salts with ligands such as [Cl.sup.-], P[Ph.sub.3], dba, N-heterocyclic carbenes [5, 6], phosphorus and/or oxygen based ligands [1, 7],
thiosemicarbazones [7], and bis(thio)urea ligands [8] in the presence of organic and/or inorganic bases for neutralization of the reaction.
