  • Carboxymethylcellulose-supported palladium nanoparticles generated <i>in situ</i> from palladium(II) carboxymethylcellulose as an efficient and reusable catalyst for ligand- and base-free Heck-Matsuda and Suzuki-Miyaura couplings
    作者:Jinlong Xiao、Zhangxiu Lu、Zhipeng Li、Yiqun Li
    DOI:10.1002/aoc.3346
    日期:2015.9
    A novel palladium(II) carboxymethylcellulose (CMC‐PdII) was prepared by direct metathesis from sodium carboxymethylcellulose and PdCl2 in aqueous solution. Its catalytic activities were explored for Heck–Matsuda reactions of aryldiazonium tetrafluoroborate with olefins, and Suzuki–Miyaura couplings of aryldiazonium tetrafluoroborate with arylboronic acid. Both reactions proceeded at room temperature
    通过溶液中羧甲基纤维素和PdCl 2的直接复分解制备了一种新型的羧甲基纤维素(II)(CMC-Pd II)。探索了其催化活性,以研究四硼酸芳基重氮鎓与烯烃的Heck-Matsuda反应,以及四硼酸芳基重氮鎓与芳基硼酸的Suzuki-Miyaura偶联。两种反应均在室温下于乙醇溶液中进行,不存在任何配体或碱,从而在大气条件下以良好或优异的收率提供相应的交叉偶联产物。CMC-Pd II和羧甲基纤维素支持的纳米粒子(CMC-Pd 0)原位形成在反应中使用傅里叶变换红外光谱,X射线衍射,电感耦合等离子体原子发射光谱以及扫描和透射电子显微镜对它们进行了表征。通过Hg(0)和CS 2中毒测试确认了CMC-Pd 0催化剂的均相性质。此外,CMC-Pd 0催化剂可通过简单过滤方便地回收,并在铃木-宫浦反应中至少重复使用十个循环,而不会明显丧失其催化活性。该催化体系不仅克服了均相催化剂回收
  • Atomically precise palladium nanocluster catalyzed tandem oxidation processes of alcohols and phosphorous ylides: Facile access to α,β-unsaturated esters
    作者:Taiping Gao、Jialei Du、Wenyan Liu、Mingxia Ren
    DOI:10.1016/j.tetlet.2020.152385
    日期:2020.10
    mesoporous silica nanosphere supported palladium nanocluster was synthesized through a simple impregnation method and well characterized. The as prepared catalyst shows excellent catalytic performance in tandem oxidation process (TOP) of alcohol and phosphorous ylide, which provides an efficient access to α,β-unsaturated esters with high yields utilizes 1 atmosphere of molecular oxygen as sole oxidant
    通过简单的浸渍方法合成了介孔二氧化硅纳米球负载的纳米簇,并对其进行了很好的表征。所制备的催化剂在醇和亚酰的串联氧化过程(TOP)中显示出优异的催化性能,利用1个大分子的分子氧作为唯一氧化剂,可以高效地高效获得α,β-不饱和酯。这项工作代表了原子精确的纳米簇催化的醇和的串联氧化过程的第一个实例,有望为串联反应中的纳米团簇开辟新的视野。

    作者:Wan-Ying Tang、Ling Chen、Ming Zheng、Le-Wu Zhan、Jing Hou、Bin-Dong Li
    DOI:10.1021/acs.orglett.1c01096
    日期:2021.5.21
    A photoinduced oxidative alkoxycarbonylation of alkenes initiated by intermolecular addition of alkoxycarbonyl radicals has been demonstrated. Employing alkyl formates as alkoxycarbonyl radical sources, a range of α,β-unsaturated esters were obtained with good regioselectivity and E selectivity under ambient conditions.
    已经证明了通过分子间加成烷氧基羰基引发的烯烃的光诱导氧化烷氧基羰基化。利用烷基甲酸酯作为烷氧羰基自由基源,在环境条件下获得了一系列具有良好区域选择性和E选择性的α,β-不饱和酯。
  • Phosphine-mediated partial reduction of alkynes to form both (<i>E</i>)- and (<i>Z</i>)-alkenes
    作者:Brett M. Pierce、Brittany F. Simpson、Kane H. Ferguson、Rachel E. Whittaker
    DOI:10.1039/c8ob01848k
    日期:——
    phosphine-mediated partial reduction of alkynyl carbonyls to the corresponding alkenes was developed. Tuning of the reaction conditions led to either the (E)- or (Z)-diastereomer with high selectivity. A range of alkynyl esters, amides, and ketones were reduced to form alkenes in good to high yields and with excellent functional group tolerance.
    已开发出温和的,膦介导的炔基羰基部分还原为相应的烯烃的方法。反应条件的调节导致具有高选择性的(E)-或(Z)-非对映异构体。还原了一系列炔基酯,酰胺和酮,以高到高收率并具有出色的官能团耐受性形成了烯烃。
  • Highly E-selective solvent-free Horner–Wadsworth–Emmons reaction catalyzed by DBU
    作者:Kaori Ando、Kyohei Yamada
    DOI:10.1039/c1gc15134g
    日期:——
    The solvent-free Horner–Wadsworth–Emmons reaction of triethyl phosphonoacetate with a variety of aldehydes was catalyzed by DBU in the presence of K2CO3 to give E-α,β-unsaturated esters highly selectively (99:1 for most of the reactions). The reaction with ketones gave trisubstituted olefins with good to high E-selectivity by DBU-Cs2CO3.
    这 溶剂无Horner–Wadsworth–Emmons的反应 膦酸三乙酯 与各种 醛类DBU在K 2 CO 3的存在下催化得到E -α,β-不饱和酯类高度选择性(大多数反应为99 :1)。与之反应酮类 给出三取代 烯烃DBU-Cs 2 CO 3具有良好的电子选择性,甚至具有很高的电子选择性。
