Organometallic chemistry of bis(N-heterocyclic carbene) ligands containing a heteroarene spacer

Heteroarene-linked bis(N-heterocyclic carbenes) constitute an important family of ligands in transition metal chemistry and homogeneous catalysis. These ligands are used as multidentate ligands for the construction of mononuclear and multinuclear complexes that show unique physical properties and that are efficient catalysts for many organic transformations. A number of transition metal complexes of heteroarene-linked bis(N-heterocyclic carbene) ligands have been synthesized and structurally characterized in recent decades. In this review, we summarize the recent developments in metal complexes supported by heteroarene-linked bis(N-heterocyclic carbene) ligands and their applications.

A Defective Linear Pentachromium Complex for the Enhanced Catalysis of the Cycloaddition of CO2 with Propylene Oxide

Based on the ligand (2,7-bis(alpha-pyrimidylamino)-1,8-naphthyridine (H(2)bpmany)), a linear pentachromium complex [Cr-5(mu(5)-bpmany)(4)Cl-2]PF6(1, mu(5)-bpmany = 2,7-bis(a-pyrimidylamino)-1,8-naphthyridine) was synthesized. The crystal structure of compound 1 has been characterized by X-ray crystallography. Interestingly, one metal atom in the center is missing in this linear chain, leading to the defective pentachromium metal string structure which is similar with the reported complex [Cr-5(mu(5)-dpznda)(4)Cl-2] (2, dpznda = N-2,N-7-di(pyrazin-2-yl)-1,8-naphthyridine-2,7-diamine). The central Cr(III) ion of 1 is eight-coordinated and is also rare in the chromium complex. The reaction of carbon dioxide with propylene oxide that generates propylene carbonate (PC) when catalyzed by [Cr-5(mu(5)-bpmany)(4)Cl-2]PF6 was investigated. Different reaction conditions including temperature and pressure were studied to optimize the reaction conditions.

SYNTHESIS, DNA BINDING, AND CLEAVAGE STUDIES OF Co(III) COMPLEXES WITH FUSED AROMATIC NO/NN-CONTAINING LIGANDS

Four new Co(III) complexes, namely [Co(ca)(3)](PF6)(3), [Co(phen)(2)(cq)](PF6)(3), [Co(bnp)(3)] (PF6)(3), and [Co(phen)(2)(bnp)](PF6)(3) (where cq = chromeno[2,3-b]quinoline, phen = 1,10-phenanthroline and bnp = dibenzo[b,g][1,8]naphthyridine), were synthesized and structurally characterized. Spectroscopic data suggested an octahedral geometry for all the complexes. Binding studies of these complexes with double-stranded (dc)DNA were analyzed by absorption spectra, viscosity, and thermal denaturation studies. The mulls revealed that the metal complex intercalates into the DNA base stack as intercalator. The oxidative cleavage activities of the complexes were studied with supercoiled pUC19 DNA using gel electrophoresis and the results show that the complexes have potent nuclease activity.

Synthesis of unsymmetrical 1,8-naphthyridine-based ligands for the assembly of tri-and tetra-nuclear copper(II) complexes

A synthetic route to unsymmetrical 1,8-naphthyridine spacer based ligands is presented. Reaction of a 7-ethyldipyridyl-1,8-naphthyridine-2-carboxaldehyde intermediate with 2-aminophenol or 4,6-di-tert-butyl 2-aminophenol led to the formation of ligands, HL1 and HL2, respectively. Both combined two distinct binding sites: a dipyridyl and an iminophenol site linked through a 1,8-naphthyridine spacer. Treatment of HL1 with copper(II) triflate in the presence of triethylamine/H2O in acetonitrile afforded a tetranuclear complex (1(tox)center dot 2CH(3)CN). X-ray analysis revealed that the structure is constituted by the association of two identical dinuclear units in which the imine is oxidized to an amide group during the complexation. The coordination capabilities of the corresponding free amide ligands H2L1ox and H2L2ox, prepared by an independent route, were explored using copper(II) triflate in the presence of triethylamine/H2O. With the amide ligand, H2L1ox, a similar tetranuclear copper complex (1(tox)center dot 2DMF) compared to the one isolated after complexation with the imine ligand HL1 was formed, as evidenced by X-ray diffraction studies. In contrast, H2L2ox, where the amido phenol arm exhibits two additional tert-butyl groups, has allowed the formation of a trinuclear copper complex (2(triox)center dot H2O).
