2-Phenylthiazole reacts with palladium(II) acetate to give a new cyclopalladated, acetato-bridged binuclear complex, <2> .A chloro-bridged analogue, <2>, produced by the reaction of the acetato-bridged complex with sodium chloride, undergoes bridge-splitting reactions with triphenylphosphine, 3,5-lutidine, and thallium(I) acetylacetonate to give the corresponding mononuclear cyclopalladated complexes.All the new complexes were characterized by means of elemental analysis, and IR and NMR spectroscopy.Reactions of <2> with methyl vinyl ketone and styrene afford 2-phenylthiazole and 2-(2'-thiazolyl)stilbene, respectively.
