الوصف: The synthesis of Ni(II) and Pd (II) coordination complexes containing Schiff's bases derived from the condensation of 2,4‐dihydroxybenzaldehyde with 4‐chloroaniline ( L1 ) or 3,5‐dichloroaniline ( L2 ) is described. The condensation of ligands L1 and L2 with chlorodiisopropylphosphine in the presence of a base produced the corresponding non‐symmetric pincer ligands POCOP‐1 and POCOP‐2 with the unexpected C−P bond formation by a hydrophosphorylation of the imine process. The new C−P bond formation probably occurring by a Kabachnik‐Field mechanism type without the requirement of catalysts or additional reagents. Further treatment of ligands POCOP‐1 or POCOP‐2 with NiCl 2 afforded the non‐symmetric pincer complexes Ni(II)‐POCOP‐1 and Ni(II)‐POCOP‐2 . The crystal structures of L1 , 3 , Ni(II)‐POCOP‐1 and Ni(II)‐POCOP‐2 were unequivocally determined by single crystal X‐ray diffraction studies. In addition, the metal complexes were used as catalysts in Suzuki‐Miyaura couplings under microwave irradiation, being the Pd(II) derivatives the best catalysts of the series when compared to their Ni(II) analogues under the same reaction conditions.
