A new family of ferrocenylated P^{^}N ligands where the nitrogen donor is either of an imine or amine (secondary/tertiary), was synthesized. The condensation reaction between diphenylphosphino propylamine and formyl ferrocene led to the formation of imine ligand [(η⁵-C₅H₅)Fe{(η⁵-C₅H₄)CH=N-(CH₂)₃-PPh₂)}] (1), which on reduction with NaBH₄ gave secondary amine ligand [(η⁵-C₅H₅)Fe{(η⁵-C₅H₄)CH₂-NH-(CH₂)₃-PPh₂)}] (2). Additionally, nucleophilic substitution reaction of diphenylphosphino ethyl/propyl amine with [FcCH₂NMe₃⁺][I⁻] salt leads to tertiary-amine ligand [(η⁵-C₅H₅)Fe(η⁵-C₅H₄)CH₂]₂-N-(R-PPh₂) where R= C₂H₄ (3) and C₃H₆ (4). The newly synthesized ferrocenylated ligands were then complexed with Pd(II) giving [cis(κ²-P^N)PdCl₂] type complexes (5-8), where imine, secondary amine, and tertiary amine ligands act as a bidentate ligand. The molecular structures of ligand (3), and complexes (5), (6), and (7) have also been determined by X-ray crystallography. In the molecular structures of these complexes, the Pd(II) center presents a distorted square-planar geometry. During the isolation of ligand (4), corresponding phosphine oxide (4A) along with a phosphonium salt (4B) was also isolated as by-products and were characterized by X-ray crystallography. The preliminary catalytic evaluation of complex (7) in the Suzuki-Miyaura cross-coupling reaction of arylboronic acids with aryl bromides was performed.

合成了新的二茂铁基化的P ^{^} N配体家族，其中氮供体为亚胺或胺（仲/叔）。导致亚胺配体的形成二苯基膦基丙胺和二茂铁酰基之间的缩合反应[（η ⁵ -C ₅ H ^ ₅）的Fe {（η ⁵ -C ₅ H ^ ₄）CH = N-（CH ₂）₃ -PPh ₂） }]（1），其在减少用NaBH ₄，得到仲胺配体[（η ⁵ -C ₅ H ^ ₅）的Fe {（η ⁵ -C ₅ H ^ ₄）CH ₂-NH-（CH ₂）₃ -PPh ₂）}]（2）。另外，进行亲核取代反应二苯基膦基乙基/丙基胺与[FCCH ₂ NME ₃ ⁺ ] [I ^- ]盐导致叔胺配体[（η ⁵ -C ₅ H ^ ₅）的Fe（η ⁵ -C ₅ H ^ ₄） CH ₂ ] ₂ -N-（R-PPh ₂），其中R ＝ C ₂ H ₄（3）和C ₃ H ₆（4）。然后将新合成的二茂铁基化的配体与Pd（II）络合，得到[顺式（κ ² -P ^ N）的PdCl ₂ ]型配合物（5-8），其中亚胺，仲胺和叔胺的配体作为二齿配体。配体（3）和配合物（5），（6）和（7）的分子结构也已经通过X射线晶体学测定。在这些配合物的分子结构中，Pd（II）中心呈现出扭曲的正方形平面几何形状。在分离配体（4）的过程中，还分离出副产物膦氧化物（4A）和a盐（4B），并通过X射线晶体学表征。在芳基硼酸与芳基溴化物的Suzuki-Miyaura交叉偶联反应中，对配合物（7）进行了初步催化评估。
