to [Pd(dba)2] (dba = dibenzylideneacetone). The addition of AgBF4 to the arylpalladium(II) complexes [PdIAr(bpy)] (Ar = C6H4-4-OMe, C6H4-2-OMe, 1-naphthyl) produces the intermolecular coupling products of the aryl ligands, Ar–Ar. The reactions of AgBF4 with the aroylpalladium(II) complexes [PdI(COAr)(bpy)] (Ar = C6H3-3,5-Me2, C6H4-2-OMe) result in decarbonylation and intermolecular coupling of the
芳基钯 (II) 络合物 [PdIAr(bpy)] (Ar = Ph, C6H3-3,5-Me2, C6H4-4-OMe, C6H4-2-OMe, C6H4-4-C6H4-4-I, 1-naphthyl ; bpy = 2,2'-联吡啶) 将 CO 和 CNR (R = tBu, C6H3-2,6-Me2) 插入 Pd-芳基键以产生 [PdI(COAr)(bpy)] 和 [PdI C(=N–R)Ar}(bpy)]。双核配合物[C6H3-3,5-(OCH2CH2)2C6H4-3-PdI(bpy)}2]是通过1,3-双[(3-碘苯基)-1,4,7的氧化加成反应合成的-三氧杂庚基]苯转化为[Pd(dba)2](dba = 二亚苄基丙酮)。将 AgBF4 添加到芳基钯 (II) 配合物 [PdIAr(bpy)](Ar = C6H4-4-OMe、C6H4-2-OMe、1-萘基)中会产生芳基配体 Ar-Ar
