    摘要:
    将官能团结合到离散的超分子配位笼(SCC)的腔中将带来独特的功能和应用。这里,三二个羧酸配体(H 2 L1氯,H 2 L2氯和H 2 L3包含N-杂环卡宾Cl)的(NHC)的前体作为接头是由两个相结合引入构建体的SCC Ç 3 -symmertic(CpZr)3(μ 3 -O)(μ 2 -OH)3簇三连接顶点,导致了一系列橄榄球状的V 2 ë 3(V =顶点,E =边缘)型均配笼(SCC-1,SCC-2和SCC-3)。但是,当相应的NHC-gold(I)功能化的配体(H 2 L1 Au,H 2 L2 Au)时,获得了包含六个Au-NHC部分的V 4 E 6型四面体笼(SCC-4和SCC-5))被应用。首次,我们提出了一个可跟踪的CpZr笼到笼的转换,以从两个具有不同V 2 E几何形状的均化笼(SCC-2和SCC-5)中生成一个杂合V 2 E 3笼(SCC-6)。3和V 4 E 6。杂合剂组

    摘要:
    我们已经报道了独特的Zn(II)金属环(1)的合成和结构表征,以及其作为荧光探针用于Fe3 +和IO4-离子的形状特异性选择识别(关闭)的用途。相关的斯特恩-沃尔默图表明,Fe3 +和IO4-离子的识别分别是两相和单相淬灭的例子。通过新型N-杂环卡宾前体1,3-双(2,6-二异丙基-4-(吡啶-4-基)苯基)-1H-咪唑-3-氯化铵的反应制备了标题金属环/溴化物(L)和氯化锌(II)盐。值得注意的是,配体本身对任何离子均未显示出任何类型的识别。使用从单晶X射线衍射数据获得的几何参数,对L和金属环氧化物1进行了DFT计算,了解配体和大环的电子结构。测定Fe3 +离子的检出限为2.5×10-6 mol / L,IO4-离子的检出限为6.3×10-5 mol / L。

  • Light‐Driven <i>gem</i> Hydrogenation: An Orthogonal Entry into “Second‐Generation” Ruthenium Carbene Catalysts for Olefin Metathesis
    作者:Raphael J. Zachmann、Alois Fürstner
    DOI:10.1002/chem.202101176
    日期:2021.5.17
    The newly discovered light‐driven gem hydrogenation of alkynes opens an unconventional yet efficient entry into five‐coordinate Grubbs‐type ruthenium carbene complexes with cis‐disposed chloride ligands. Representatives of this class featuring a chelate substructure formed by an iodo‐substituted benzylidene unit react with (substituted) 2‐isopropoxystyrene to give prototypical “second‐generation” Grubbs‐Hoveyda
    新发现的炔烃的光驱动宝石氢化为非常规而高效地进入具有顺式配置的配体的五坐标Grubbs型卡宾配合物提供了条件。这类代表的特征是由取代的亚苄基单元形成的螯合物亚结构与(取代的)2-异丙氧基苯乙烯反应,生成原型的“第二代” Grubbs-Hoveyda络合物,用于烯烃复分解。这个古老的催化剂家族的新方法是安全和通用的,因为它使用三键而不是苯基重氮甲烷作为最终的卡宾源,并且不需要任何牺牲膦。

  • Reductive Cyclization of Diynes and Enynes Catalyzed by Allyl Platinum N-Heterocyclic Carbene Complexes
    作者:Il Gu Jung、Junhyeok Seo、Sang Ick Lee、Soo Young Choi、Young Keun Chung
    DOI:10.1021/om0606284
    日期:2006.8.1
    Platinum N-heterocyclic carbene (NHC) complexes have been synthesized and used as precatalysts in the reductive cyclization of diynes and eynes. 2,5-Dihydrofurans, -pyrroles, and -cyclopentenes were obtained as reductive cyclization products from oxygen-, nitrogen-, and carbon-tethered substrates, respectively. The yield and product of the reaction were highly dependent upon the substrate and the substituent on the alkyne.

According to the method of the present invention, a high molecular weight cyclic olefin addition polymer can be produced in a high yield even when using a polar functional group-containing cyclic olefin monomer. A polymer produced using the method shows good thermal stability.
