The ligands 2-(arylazo)-1-N-salicylidene phenylamine, H2Lsal, (where H represents the dissociable protons upon complexation) afford stable orthopalladated complexes, [(Lsal)Pd], upon treatment with Na2[PdCl4]. The dinegative anionic (Lsal)2− ligands bind Pd(II) in a tetradentate (C, N, N, O) fashion with a distorted square planar geometry. The newly synthesized palladium complexes underwent oxygen insertion into the Pd–C bond with mCPBA (m-chloroperbenzoic acid) or TBHP (terbutylhydroperoxide)/[VO(acac)2] leading to the formation of stable azosalophen complexes of Pd(II) with the (O, N, N, O) coordination mode of the oxygenated ligand.
Graphical abstractSynthesis of stable metal–carbon bonded complexes and studies on their reactivity have drawn interest due to multifaceted utilities. Herein the new azosalophen complexes of Pd(II) have been synthesized using the principle of oxygen insertion into the Pd–C bond.Figure optionsDownload full-size imageDownload as PowerPoint slide
