Cationic (carbene) organopalladium(II) complexes coordinated with cyclic diolefin or organic nitrile

The chloro-bridged (carbene)organopalladium(II) complex, di-μ-chlorobis(1,3-diphenyl-2-imidazolidinylidenato-2-C,2′-C)dipalladium(II) underwent chlorine abstraction with silver perchlorate in the presence of a cyclic diolefin or an organic nitrile, to give new cationic (carbene)organopalladium(II) complexes coordinated with the respective substrates. These new complexes were characterized by means of elemental analysis, molar conductivities, and IR and ¹H NMR spectroscopy.
