Abstract

In the presence of large amounts of [Me₄N]Cl, the reaction of ortho-chloromercurated 2-[(η⁶-phenyl)tricarbonylchromium]pyridine with μ-chloro cyclopalladated aromatic compounds yields a series of new heteroleptic heterodinuclear cis-(C⁁N)₂Pd(II) complexes, which are valuable precursors of planar chiral cyclopalladated (η⁶-arene)Cr(CO)₃ complexes.
