    Insight into Water Oxidation by Mononuclear Polypyridyl Ru Catalysts
    摘要:
    A family of compounds based on the mononuclear coordination complex [Ru(tpy)(bpy)(OH2)](2+) (1b; tpy=2,2':6',2 ''-terpyridine, bpy=2,2'-bipyridine) are shown to be competent catalysts in the Ce(IV)-driven oxidation of water in acidic media. The systematic installation of electron-withdrawing (e.g., -Cl, -COOH) and -donating (e.g., -OMe) groups at various positions about the periphery of the polypyridyl framework offers insight into how electronic parameters affect the properties of water oxidation catalysts, It is observed, in general, that electron-withdrawing groups (EWGs) on the bpy ligands suppress catalytic activity (k(obs)) and enhance catalytic turnover numbers (TONs); conversely, the presence of electron-donating groups (EDGs) accelerate catalytic rates while decreasing catalyst stability. We found that 2,2'-bipyridine N,N'-dioxide is produced when 1b is subject to excess Ce(IV) in acidic media, which suggests that dissociation of the bpy ligand is a source of catalyst deactivation and/or decomposition. Density functional theory (DFT) calculations corroborate these findings by showing that the Ru-N-bpy bond trans to the O atom is weakened at higher oxidation levels while the other Ru-N bonds are affected to a lesser extent. We also show that the Ru-Cl bond is not robust in aqueous media, which has implications in studying the catalytic behavior of systems of this type.

  • The synthesis of 4′-aryl substituted terpyridines by Suzuki cross-coupling reactions: substituent effects on ligand fluorescence
    作者:Wendy Goodall、Kerstin Wild、Kathryn J. Arm、J. A. Gareth Williams
    DOI:10.1039/b205330f
    日期:——
    Several 4′-aryl-substituted 2,2′:6′,2″-terpyridines (tpy-C6H4R) have been prepared by palladium-catalysed cross-coupling of 4′-bromoterpyridine or 4′-triflate-terpyridine (triflate = trifluoromethylsulfonyloxy) with aryl boronic acids or esters, RC6H4B(OR′)2 (R = H, m-NH2, p-CHO, -NO2, -CN, -NMe2, -NPh2). The new ligand 4′-mesitylterpyridine (mesityl = 2,4,6-trimethylphenyl) was prepared in the same way. Similarly, 4′-bromophenylterpyridine (tpy-ϕ-Br) has been cross-coupled with aryl halides to generate several new biaryl-substituted terpyridines (tpy-ϕ-C6H4R where R = H, p-CN, NMe2, NPh2), together with two related compounds with pendent 3- or 4-pyridyl groups (tpy-ϕ-C6H4-py). For selected compounds, the alternative coupling strategy of reaction of a terpyridine-4-boronate or terpyridine-4-phenylboronate with the appropriate aryl halide has also been investigated (e.g. to prepare tpy-ϕ-C6H4NO2), but was generally found to be less satisfactory. All of the compounds are fluorescent in the UV region of the spectrum, the biaryl-substituted compounds being only slightly red-shifted compared to the monoaryl systems, but with the further red-shift that accompanies protonation being more significant for the former. Fluorescence lifetimes in solution are in the range 1–5 ns. The emission spectra of the aminobiphenyl-substituted compounds (tpy-ϕ-C6H4NR″2, where R″ = Me or Ph) display a large red-shift with increasing solvent polarity, suggesting the involvement of an intramolecular charge transfer state, as found previously for the two analogues omitting the phenyl ring (tpy-C6H4NR″2). In contrast to the latter, however, protonation or binding of a Lewis acidic metal ion to the aminobiphenyl compounds serves to quench almost completely their emission.
    通过钯催化的交叉偶联反应,制备了几种4′-芳基取代的2,2′:6′,2″-三联吡啶(tpy-C6H4R),涉及4′-溴三联吡啶或4′-三氟甲磺酸酯三联吡啶(triflate = 三氟甲磺酰氧基)与芳基硼酸或硼酸酯的反应,RC6H4B(OR′)2(R = H, m-NH2, p-CHO, -NO2, -CN, -NMe2, -NPh2)。新配体4′-三甲基苯基三联吡啶(mesityl = 2,4,6-三甲基苯基)也通过相同方法制备。类似地,4′-溴苯基三联吡啶(tpy-Φ-Br)已与芳基卤化物交叉偶联,生成了几种新的双芳基取代三联吡啶(tpy-Φ-C6H4R,其中R = H, p-CN, NMe2, NPh2),以及两种含有3-或4-吡啶基侧链的相关化合物(tpy-Φ-C6H4-py)。对于选定的化合物,还研究了替代的偶联策略,即反应一个三联吡啶-4-硼酸酯或三联吡啶-4-苯基硼酸酯与适当的芳基卤化物(例如制备tpy-Φ-C6H4NO2),但通常发现效果较差。所有化合物在紫外区域都有荧光发射,双芳基取代的化合物相比于单芳基系统仅有轻微的红移,但其伴随质子化产生的进一步红移对前者更为显著。溶液中的荧光寿命在1~5纳秒范围内。氨基联苯取代化合物的发射光谱(tpy-Φ-C6H4NR″2,其中R″ = Me或Ph)随着溶剂极性的增加显示出较大的红移,表明存在分子内电荷转移态,这与先前报道的两种省略苯环的类似物(tpy-C6H4NR″2)一致。然而,与后者不同,氨基联苯化合物在质子化或与路易斯酸性金属离子结合时,其发射几乎完全淬灭。

    [Ru(Rtpy)(bpy)(H2O)]2+ (1R; bpy = 2,2′-bipyridine, and Rtpy = 2,2′:6′,2″-terpyridine derivatives) complexes with a variety of 4′-substituent groups on Rtpy were synthesized and characterized to reveal the effects of substituents on their structures, physicochemical properties, and catalytic activities for water oxidation. The geometric structures of 1R are not considerably influenced by the electron-donating
    [Ru(Rtpy)(bpy)(H 2 O)] 2+(1R ; bpy = 2,2'-联吡啶,Rtpy = 2,2':6',2''-叔吡啶衍生物)配合物合成并表征了Rtpy上的4'-取代基,以揭示取代基对其结构,理化性质和对水氧化的催化活性的影响。1R的几何结构不受Rtpy上4'取代基的供电子能力影响。对于1R观察到类似的多步质子偶联电子转移反应并且,随着取代基的供电子能力的增加,每个氧化步骤的氧化还原电势趋于降低,这可以解释为供电子基团在Ru中心的电子密度增加,从而稳定了积聚的正电荷。在氧化时。这与由于Ru中心的d轨道能级增加而分配给1R的金属到配体电荷转移跃迁的480 nm附近吸收带的红移一致。然而,水氧化催化反应的1R转换频率(k O 2)很大程度上取决于Rtpy配体,范围从0.05×10 –2到44×10 –2 s –1(因为观察到R =乙氧基的最高k O 2)是880倍。4'-取代
