  Mononuclear (O,O′ or N,N′) and Heterodinuclear (O,O′ and N,N′) Transition-Metal Complexes of ortho-Quinoid Bis(pyrazol-1-yl)methane Ligands

  摘要：

  The ortho-hydroquinone-substituted bis(3,5-dimethylpyrazol-1-yl)methane ligand (HO)(2)C6H3-C(H)-(Pz(Me,Me))(2) (7) has been synthesized and fully characterized. Together with its bis(3-tert-butylpyrazol-1-yl)methane congener (HO)(2)C6H3-C(H)(pz(tBu))(2) (6), 7 was employed in oxidation and complexation studies. 6 has been oxidized with 2,3-dichloro-5,6-dicyano-para-benzoquinone to the corresponding ortho-benzoquinone form 9 on a preparative scale. Pure samples of 9 are stable for several hours in solution and for approximately one day in the solid state. Attempts at a N,N' coordination of [PdCl2] to 6 led to decomposition of the -C(H)(pz(tBu))(2) moiety, whereas an introduction of [PdCl2] exclusively at the N,N' site was possible in high yield for ligand 7. A selectively O,O'-chelated [(p-cym)Ru](2+) complex was accessible for ligand 6, but not for 7. In contrast, [(ppy)(2)Ir](+) and [(Cp*)Ir](2+) gave O,O' complexes with both donors 6 and 7 (Hppy = 2-phenylpyridine; HCp* = pentamethylcyclopentadiene). The heterodinuclear complex [(Cp*)Ir(O)(2)C6H3-C(H)(pz(Me,Me))(2)PdCl2] (16) was obtained from 14 and [(MeCN)(2)PdCl2].
