It has been shown that in some applications recrystallized palladium(ll) acetate, Pd(OAc)2, performs better than typical grades. White and Overman have both independently demonstrated that in some applications a particular grade of Pd(OAc), is necessary. In particular, the preparation of the White catalyst as well as the preparation of the COP catalysts-[COP-OAc]2 and [COP-Cl]2 by Overman successfully employ and require recrystallized Pd(OAc)2.
