A strategy of Pd(II) assisted C–H activation in 2-alkylamino azobenzene ligands: Syntheses, characterisation and structure of a new family of orthopalladated complexes
Several 2-(arylazo)-N-alkyl aniline ligands, 1a-11a, have been prepared by the reaction between 2-(arylazo) aniline and the appropriate alkyl halide in the presence of K2CO3. Treatment of sodium tetrachloropallaclate with 1a-11a in methanol afforded the orthopalladated complexes 1b-11b, where the ligand is tridentate (C,N,N). The ligands and complexes were characterised from spectroscopic data and confirmed by X-ray studies. The X-ray Structure of 9b displayed an unsupported Pd(II)Pd-...(II) interaction (3.301 angstrom).

HLnNHCH2Ph with K2PtCl4 in dmso also gives [(HLnNH)Pt(dmso)Cl] whereas Na2PdCl4 affords the orthopalladated complexes [(LnNHCH2Ph)PdCl]. This means that the N–C(CH2Ph) bond is selectively cleaved by K2PtCl4. The reaction of [(HLnNH)Pt(dmso)Cl] with acetylacetone (acacH) gives the heteroleptic complex [(HLnNH)Pt(acac)]. [(HLnNH)Pt(dmso)Cl] and [(HLnNH)Pt(acac)] display a reversible reductive response at
