3-Phenyl-6-p-toluidinopyridazine (abbreviated as Hptp) was prepared as an ambidentate substrate of cyclometallation. Sodium tetrachloroaurate(III), gold(III) bromide, lithium tetrachloropalladate(II), and rhodium(III) chloride cyclometallated Hptp to give [Au(ptp)Cl2], [Au(ptp)Br2], [Pd(ptp)Cl], and [Rh(ptp)2Cl], respectively. These complexes and [Pd(ptp)Cl(PBu3)] (PBu3 = tri-n-butylphosphine) were characterized spectroscopically. The square-planar structures of [Au(ptp)Br2]·(CH3)2SO and [Pd(ptp)Cl(PBu3)]·CH3OH were determined by X-ray analysis. Cycloauration preferred forming a six-membered metallacycle while cyclopalladation and cyclorhodation formed five-membered metallacycles.
