  Facile regiospecific aromatic hydroxylation in palladium azopyridines and structural characterization of phenolato product

  摘要：

  The reaction of Na2PdCl4 with 2-(arylazo)pyridines (A) in ethanol affords yellow complexes of composition [PdACl2] in which the PdCl2 fragment has a cis configuration [nu(Pd-Cl): 350, 365 cm-1]. Upon treating [PdACl2] with dilute sodium hydroxide in air the pendent aryl group is selectively hydroxylated at the ortho position, affording the phenolato complex [PdBCl] in high yields [B- is deprotonated 2-(2'-hydroxyarylazo)pyridine]. A possible reaction pathway is proposed by analogy with the hydroxylation of certain organic compounds by OH-/O2. The crystal and molecular structure of one [PdBCl] complex is reported. In the highly planar complex, the Pd-N(azo) length is significantly shorter than the Pd-N(pyridine) length. A single Pd-Cl stretch at 365 cm-1 characterizes [PdBCl] which, unlike [PdACl2], has a structured intense absorption in the visible region near 670 nm.
