Palladium Dichloride 以 乙腈 用作溶剂,化学反应生成双(乙腈)氯化钯(II) 参考文献:Structure,Dynamics And Catalytic Activity Of Palladium(II) Complexes With Imidazole Ligands 标题:Structure,Dynamics And Catalytic Activity Of Palladium(II) Complexes With Imidazole Ligands 摘要:Several Palladium Complexes Of The Type [pd(Im)(2)Cl-2],[pd(Im)(3)Cl]Cl,And [pd(Im)(4)]Cl-2 (Im = Imidazole 1,1-Methylimidazole 2,1,2-Dimethylimidazole 3,1-Butylimidazole 4,4A,1-Phenylimidazole 6,1-Phenylimidazoline 7,And 1-Methylimidazoline 8) Were Prepared And Structurally Characterized. The Square Planar Structure Of Two New Complexes With The Composition [pd(Im)(4)]Cl-2 (2B,4B) Was Confirmed By X-Ray Analysis. In Solution,Exchange Of Imidazole Ligands Leading To Heteroleptic Products Was Evidenced By Esi-Ms Studies. Two Bis-Ligated Complexes,Bearing 1-Methylimidazole (2A) And 1-Propoxymethylimidazole (5) Ligands,Were Obtained In The Reaction Of Palladium With Imidazoles Formed By Deprotection Of One Nitrogen Atom In The Respective Imidazolium Halides. Catalytic Suzuki-Miyaura Reactions Were Carried Out Using The Obtained Palladium Complexes In Isopropanol-Water Solution. High Yields Of The Cross-Coupling Products Were Obtained At 40 And 60 Degrees C When 2-Bromotoluene,4-Bromotoluene,And 4-Bromoanizole Were Used As Substrates. (C) 2010 Elsevier B.V.
