  摘要：

  尽管其用途广泛，邻醌的合成仍然是一个重大挑战，特别是获得缺电子衍生物仍然是一个未解决的问题。这里报道了第一个通过酚类直接氧化合成缺电子邻醌的通用方法。该反应是通过一种新型双齿氮连接碘 (V) 试剂实现的，这是一类以前未开发的化合物，我们将其称为 Bi( N )-HVI。该反应非常普遍，并且对于邻位异构体和对位异构体具有优异的区域选择性。对邻醌产物的官能化进行了检查，从而实现了儿茶酚的简单一锅合成，以及多种杂原子亲核试剂的掺入。该方法代表了 Bi( N )-HVI的首次合成应用，并展示了它们作为进一步开发高反应性、高度可调的 I(V) 试剂的平台的潜力。

• Synthesis and Characterization of a Series of Bis-homoleptic Cycloruthenates with Terdentate Ligands as a Family of Panchromatic Dyes

  A series of six homoleptic bis-cyclometalated ruthenium complexes, Ru(N^N^C)2, is reported where N^N^C is a 6-(2,4-difluoro-3-R3-phenyl)-4-R2-4′-R1-2,2′-bipyridine with R3 = −H or −CF3 and R2 and R1 = −COOEt or −CF3. An effective synthesis of the ligands and the complexes is described. The UV–visible absorption studies demonstrate that these complexes are panchromatic dyes absorbing up to 900 nm. Importantly

  报道了一系列六个均一的双环金属化钌络合物Ru（N ^ N ^ C）2，其中N ^ N ^ C是6-（2,4-二氟-3-R 3-苯基）-4- R 2 -4'-R 1 -2,2'-联吡啶，其中R 3 = -H或-CF 3且R 2和R 1 = -COOEt或-CF 3。描述了配体和配合物的有效合成。紫外可见吸收研究表明，这些络合物是吸收高达900 nm的全色染料。重要的是，吸收的开始仅取决于金属化苯基上的取代，而整个光谱的吸收强度是苯基和联吡啶部分上的取代基的函数。在电化学中观察到相同的趋势，因为氧化还原间隙仅取决于金属化苯基上的取代，而氧化和还原电势是苯基和联吡啶部分上的取代基的函数。用作染料敏化太阳能电池敏化剂的初步测试表明，染料上的锚定基团数量对器件效率有重要影响。

  reactions. The most streamlined approach for the synthesis of 2,2′‐bipyridyls is the dehydrogenative dimerization of unfunctionalized pyridine. Herein, we report on the palladium‐catalyzed dehydrogenative synthesis of 2,2′‐bipyridyl derivatives. The Pd catalysis effectively works with an AgI salt as the oxidant in the presence of pivalic acid. A variety of pyridines regioselectively react at the C2‐positions

  2,2'-联吡啶已被用作金属催化反应中必不可少的配体。合成2,2'-联吡啶的最简化方法是未官能化吡啶的脱氢二聚作用。在这里，我们报道了钯催化的2,2'-联吡啶衍生物的脱氢合成。在新戊酸存在下，Pd催化有效地以Ag I盐为氧化剂。多种吡啶在C2位置发生区域选择性反应。这种二聚方法适用于具有挑战性的底物，例如空间受阻的3-取代的吡啶，其中吡啶在C2位上发生区域选择性反应。该反应使简明的合成3,3'-di取代-2,2'-联吡啶作为一种不发达的配体。

  Thiocyanate-free isoquinazolylpyrazolate Ru(II) complexes were synthesized and applied as sensitizers in dye-sensitized solar cells (DSCs). Unlike most other successful Ru sensitizers, Co-based electrolytes were used, and resulting record efficiency of 9.53% was obtained under simulated sunlight with an intensity of 100 mW cm–2. Specifically, dye 51-57dht.1 and an electrolyte based on Co(phen)3 led

  合成了无硫氰酸盐的异喹唑基吡唑啉化物Ru（II）配合物，并将其用作染料敏化太阳能电池（DSC）中的敏化剂。与大多数其他成功的Ru敏化剂不同，使用了Co基电解质，在模拟的日光强度为100 mW cm –2的情况下，记录效率为9.53％。具体来说，染料51-57dht.1和基于Co（phen）3的电解质导致J SC的测量值为13.89 mA cm –2，V OC900 mV的FF和0.762的FF产生9.53％的效率。器件性能的改善是通过在异喹啉亚基上包含2-己基噻吩单元，以及延长吡唑酸酯螯合基团上的全氟烷基链来实现的，这在使用Co基电解质时起到了增加光吸收和降低重组效果的作用。如本研究所示，带有空间要求的配体的Ru（II）敏化剂可以成功地利用重要的Co电解质和高性能。

  The synthesis of asymmetrically substituted 2,2′:6′,2′′‐terpyridines is reported. First, palladium‐catalyzed CH arylation of pyridine N‐oxides with substituted bromopyridines gave 2,2′‐bipyridine N‐oxides, which were further arylated in a second step to form 2,2′:6′,2′′‐terpyridine N‐oxides. Yields of up to 77 % were obtained with N‐oxides bearing an electron‐withdrawing ethoxycarbonyl substituent

  报道了不对称取代的2,2'：6'，2''-叔吡啶的合成。首先，钯催化的C ^  ħ吡啶芳基化Ñ -oxides与取代的溴吡啶，得到2,2'-联吡啶Ñ -oxides，其中在第二步骤中进一步芳基化以形成2,2'：6'，2'' -特吡啶N-氧化物。使用在4位带有吸电子乙氧基羰基取代基的N氧化物，收率高达77％。带有P（t Bu）3或P（邻甲苯基）3的Pd（OAc）2被用作催化剂。衍生自Pd（OAc）2的环金属配合物这些膦也有效。以K 3 PO 4为碱比K 2 CO 3可获得更好的结果。随后用H 2和Pd / C作为催化剂进行脱氧，得到了接近定量收率的不对称取代的2,2'：6'，2''-吡啶。与已知的交叉偶联方法相比，该反应序列显着减少了所需的步骤数，因此可以方便且可扩展地使用取代的吡啶。

  A series of rhenium diimine carbonyl complexes was prepared and characterized in order to examine the influence of axial ligands on electronic structure. Systematic substitution of the axial carbonyl and acetonitrile ligands of [Re(deeb)(CO)3(NCCH3)]+ (deeb = 4,4′-diethylester-2,2′-bipyridine) with trimethylphosphine and chloride, respectively, gives rise to red-shifted absorbance features. These bathochromic

  制备了一系列of二亚胺羰基配合物并进行了表征，以研究轴向配体对电子结构的影响。[Re（deeb）（CO）3（NCCH 3）] +（deeb = 4,4'-diethylester-2,2'- bipyridine）的轴向羰基和乙腈配体分别被三甲基膦和氯化物系统取代出现红移的吸光度特征。这些红移是由于参与金属到配体的电荷转移跃迁的占据的d轨道不稳定而引起的。时变密度泛函理论确定了每个跃迁中涉及的轨道，并为配体取代引起的轨道能量变化提供了支持。
