- 中文摘要: Treatment of Pd(PPh3)4 with 2-bromo-4-methylpyridine, C5H3N(CH3)Br, in dichloromethane at -20 °C causes the oxidative addition reaction to produce the palladium complex [Pd(PPh3)2{η1-C5H3N(CH3)}(Br)], 2, by substituting two triphenylphosphine ligands. In a dichloromethane solution of complex 2 at room temperature for 3 h, it undergoes displacement of the triphenylphosphine ligand to form the dipalladium complex [Pd(PPh3)Br]2{μ,η2-C5H3N(CH3)}2, 3, in which the two 4-methylpyridine ligands coordinated through carbon to one metal center and bridging the other metal through the nitrogen atom. Complexes 2 and 3 are characterized by X-ray diffraction analyses.
