Commercially available palladium acetate often contains two major impurities, whose presence can impact the overall catalytic efficacy. This systematic study provides a comparison of the differences in catalytic activity of pure palladium acetate, Pd-3(OAc)(6), with the two impurities: Pd-3(OAc)(6)(NO2) and polymeric [Pd(OAc)(2)](n) in a variety of cross-coupling reactions. The solid state C-13 NMR spectra of all three compounds in conjunction with DFT calculations confirm their reported geometries.
