The compounds Pd(η3-1-Ph-C3H4)(η5-C5H5) (I), Pd2(dba)3 (II), Pd(OAc)2 (III), and [Pd(η3-1-Ph-C3H4)Cl]2 (IV) are frequently used as catalyst precursors for a variety of cross-coupling processes, including Suzuki-Miyaura, Heck-Mizoroki, Sonogashira, and Buchwald-Hartwig reactions. The NMR spectroscopy the solution chem. of I and IV with PBut3, XPhos, and Mor-Dalphos, noting similarities and differences in the resp. abilities of these precursor-ligand combinations to generate Pd(0) catalyst systems. Inter alia that steric requirements prevent Xphos and Mor-Dalphos from forming 2:1 Pd(0) complexes and, surprisingly, that 1:1 Pd(0) complexes of Xphos and Mor-Dalphos are unstable with respect to dissociation to free ligand and Pd metal were found. These two ligands and, by implication, other sterically demanding phosphine ligands do not form Pd(0) compounds
