Dipalladium(I) complexes of ortho- and para-functionalized 1,3-bis(aryl)triazenide ligands: Synthesis, structure and catalytic activity

Abstract The synthesis and characterization of a series dipalladium(I) complexes of formulae [Pd{1-[2′-(methoxycarbonyl)phenyl]-3-[4′-X-phenyl]triazenide}] 2 [X = F ( 4 ), Cl ( 5 ), Br ( 6 )] are reported. The crystal structure of complex 4 was determined by X-ray diffraction studies. The previously reported dipalladium(I) 1 – 3 as well as the new complexes 4 – 6 were used as catalysts in the Heck and Suzuki couplings of different p -substituted bromobenzenes.
