    A novel palladium nanoparticle (NP)-metalated porous organic ligand (Pd NPs/POL-xantphos) has been prepared for the chemoselective decarbonylation of aldehydes. This heterogenous catalyst not only has excellent catalytic activity and chemoselectivity, but also holds high activity after 10 runs of reuse. The effective usage of this method is demonstrated through the synthesis of biofuels such as furfuryl
    一种新型的钯纳米粒子(NP)金属化的多孔有机配体(Pd NPs / POL-xantphos)已制备用于醛的化学选择性脱羰。这种多相催化剂不仅具有出色的催化活性和化学选择性,而且在重复使用10次后仍具有很高的活性。这种方法的有效使用通过合成生物燃料(例如糠醇(FFA))得到证明,该生物燃料是通过生物素衍生的5-羟基-甲基糠醛(HMF)的高化学选择性脱羰,TON达到1540。更重要的是,9-芴酮通过使用这种非均相催化剂使2-溴苯甲醛脱羰可以一步完成。
  • Highly Selective Copper-Catalyzed Hydroboration of Allenes and 1,3-Dienes
    作者:Kazuhiko Semba、Masataka Shinomiya、Tetsuaki Fujihara、Jun Terao、Yasushi Tsuji

    The highly selective copper‐catalyzed hydroboration of allenes has been developed. Allylboranes and alkenylboranes were selectively prepared by the judicious choice of catalytic species (copper hydride and boryl copper). Furthermore, two types of alkenylboranes could be selectively synthesized by the choice of an appropriate ligand. Mechanistic studies confirmed that the protonation of a (Z)‐σ‐allyl
    已经开发出高度选择性的铜催化的艾伦硼氢化。通过明智地选择催化物种(氢化铜和硼基铜)选择性地制备烯丙基硼烷和烯基硼烷。此外,可以通过选择合适的配体来选择性地合成两种类型的烯基硼烷。机理研究证实,(Z)-σ-烯丙基铜的质子化是这些反应的关键步骤,该质子是通过单晶X射线衍射分离并在结构上表征的。除丙二烯外,该方法还适用于1,3-二烯衍生物的选择性加氢硼化反应,制得烯丙基硼烷和高烯丙基硼烷。
  • Porous Organic Polymer as a Heterogeneous Ligand for Highly Regio- and Stereoselective Nickel-Catalyzed Hydrosilylation of Alkyne
    作者:Yun-Bing Zhou、Zhi-Kai Liu、Xin-Yang Fan、Ren-Hao Li、Guo-Liang Zhang、Li Chen、Ying-Ming Pan、Hai-Tao Tang、Jia-Hao Zeng、Zhuang-Ping Zhan
    DOI:10.1021/acs.orglett.8b03064
    日期:2018.12.21
    A porous organic polymer (POL-Xantphos) was synthesized and employed as a heterogeneous ligand for selective hydrosilylation of alkynes. It exhibits high selectivity and catalytic efficiency toward a broad range of alkynes. Owing to the confinement effect of the micropore structure, POL-Xantphos was far superior to the monomeric Xantphos ligands in controlling the selectivity. By performing hydrosilylation
    合成了多孔有机聚合物(POL-Xantphos),并用作炔烃的选择性氢化硅烷化的异质配体。它对多种炔烃具有高选择性和催化效率。由于微孔结构的限制作用,POL-Xantphos在控制选择性方面远远优于单体Xantphos配体。通过在流动反应器系统中进行氢化硅烷化,可以轻松实现Ni / POL-Xantphos催化剂的分离和再生,而不会损失选择性或活性。
  • Xantphos Doped POPs-PPh<sub>3</sub> as Heterogeneous Ligand for Cobalt-Catalyzed Highly Regio- and Stereoselective Hydrosilylation of Alkynes

    A Co(acac)2/POL‐Xantphos@10PPh3‐catalyzed hydrosilylation of unsymmetrical internal alkynes with Ph2SiH2 has been developed for the synthesis of highly selective syn‐α‐vinylsilane products. Furthermore, terminal alkynes were also used and gave the products with excellent regioselectivity and a wide functional group tolerance. Because this porous organic polymer combines the selectivity and activity
    已经开发出了用Co 2(PH 2 SiH 2)对不对称内部炔烃进行Co(acac)2 / POL-Xantphos @ 10PPh 3催化的氢化硅烷化反应,用于合成高度选择性的合成α-乙烯基硅烷产物。此外,还使用末端炔烃,使产物具有极好的区域选择性和宽泛的官能团耐受性。因为这种多孔有机聚合物将Xantphos的选择性和活性优点与高浓度PPh 3带来的稳定性优势相结合,所以Co(acac)2 / POL-Xantphos @ 10PPh 3可以多次回收而不会损失活性和选择性。该多相催化剂有望在工业合成中找到有前途的应用。
