    摘要:
    合成了两种新型NCN型螯合配体前驱体,其骨架分别为2,6-双(噁唑-4-基)苯(A)和2-(噻唑-4-基)-6-(噁唑-4-基)苯(B),之后对A和B进行铂催化得到两种新型双唑螯合配体配合物,即[(A-κ3 NCN)PdBr](1)和[(B-κ3 NCN)PdBr](2)。两种配合物均通过核磁共振、质谱、差示扫描量热-热重分析和单晶X射线衍射进行了表征。配合物1的晶体属于非对称正交晶系Cmc21(No. 36,Z=4)。配合物2的晶体属于对称单斜晶系P21/n(No. 14,Z=4)。两种配合物的化学式相似,但结构略有不同:它们都是由具有相同拓扑结构但堆叠次序不同的二维层状超分子组成,即配合物1的堆叠次序为AAAA型,而配合2的堆叠次序为AA1 AA1 交替型(A表示一个层;A1表示A的反演对称对等)。另外,这些配合物在 Mizoroki-Heck 反应中表现出良好的催化活性。

In the solid state, the phosphinidene is coordinated by one adjacent N atom featuring a formal P−N bond (1.757(2) Å) to give a five‐membered ring with some aromatic character, confirmed by DFT calculations (B3LYP‐D3/6‐311G**++) to be the ground‐state structure. Equilibration of the two N ligands occurs rapidly in solution via a “bell‐clapper”‐type process through

    An efficient protocol for the asymmetric synthesis of fluorenols has been developed through an enantioconvergent process enabled by Pd(II)/chiral norbornene cooperative catalysis. This approach allows facile access to diverse functionalized chiral fluorenols with constantly excellent enantioselectivities, applying readily available racemic secondary ortho-bromobenzyl alcohols and aryl iodides as the

  • Catalytic Activation of N<sub>2</sub>O at a Low-Valent Bismuth Redox Platform
    作者:Yue Pang、Markus Leutzsch、Nils Nöthling、Josep Cornella
    DOI:10.1021/jacs.0c10092
    日期:2020.11.18
    Herein we present the catalytic activation of N2O at a BiI⇄BiIII redox platform. The activation of such a kinetically inert molecule was achieved by the use of bismuthinidene catalysts, aided by HBpin as reducing agent. The protocol features remarkably mild conditions (25 °C, 1 bar N2O), together with high turnover numbers (TON, up to 6700) and turnover frequencies (TOF). Analysis of the elementary steps enabled structural characterization of catalytically relevant intermediates after O-insertion, namely a rare arylbismuth oxo dimer and a unique monomeric arylbismuth hydroxide. This protocol represents a distinctive example of a main-group redox cycling for the catalytic activation of N2O.
