Ferrocenylated imine- and amine(secondary/tertiary)- phosphine P boolean AND N ligands and their Pd(II) complexes: Synthesis and structural characterization
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 [(eta(5)-C5H5)Fe[(eta(5)-C5H4)CH=N-(CH2)(3)-PPh2)}] (1), which on reduction with NaBH4 gave secondary amine ligand [((eta(5)-C5H5)Fe[(eta(5)-C5H4)CH=N-(CH2)(3)-PPh2)}] (2). Additionally, nucleophilic substitution reaction of diphenylphosphino ethyl/propyl amine with [FcCH(2)NMe(3)(+)][I-] salt leads to tertiary-amine ligand [(eta(5)-C5H5)Fe[(eta(5)-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(kappa(2)-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. (C) 2020 Elsevier B.V. All rights reserved.
