Synthesis, structure and reactivity of azosalophen complexes of palladium
摘要:
The ligands 2-(arylazo)-1-N-salicylidene phenylamine, H2Lsal, (where H represents the dissociable protons upon complexation) afford stable orthopalladated complexes, [(L-sal)Pd], upon treatment with Na-2[PdCl4]. The dinegative anionic (L-sal)(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.
