  • Easily available nickel complexes as catalysts for the intermolecular hydroamination of alkenes and alkynes
    作者:Adán Reyes-Sánchez、Ilnett García-Ventura、Juventino J. García
    DOI:10.1039/c3dt52648h
    日期:——
    A series of nickel complexes of the type [(P–P)NiX2] ((P–P) = bisphospines or bisphosphites, X = chloride, triflate) were used as catalysts for the hydroamination of both activated and unactivated alkenes and alkynes with pyrrolidine. In general, the use of activated unsaturations, such as acrylonitrile, required mild reaction conditions (e.g. 100 °C and 4 h) in comparison with other non-activated
    一系列[(P-P)NiX 2 ]类型的镍配合物((P-P)=双膦或双亚磷酸酯,X =氯化物,三氟甲磺酸酯)被用作催化剂,用于活化和未活化的烯烃和炔烃吡咯烷。通常,与其他未活化的烯烃相比,使用活化的不饱和基团(例如丙烯腈)需要温和的反应条件(例如100°C和4 h)。特别是对于一系列炔烃,使用镍(II中心减少或什至抑制了其他不希望的均偶联和/或转移氢化副产物的形成,例如在零价镍存在下获得的副产物。当使用较少活化的底物时,尽管需要更苛刻的反应条件,但可获得更好的选择性。从一般的角度来看,本报告的结果强烈支持潜在的使用镍作为通过筛选几种π受体配体进一步应用在有机不饱和键的加氢胺化反应中的良好选择。
  • Palladium-Catalyzed Additions of Terminal Alkynes to Acceptor Alkynes
    作者:Barry M. Trost、Mark T. Sorum、Chuen Chan、Gerd Rühter
    DOI:10.1021/ja9624937
    日期:1997.1.1
    The development of addition reactions wherein the product is the simple sum of the reactants plus anything else (only needed catalytically) constitutes an important goal for enhanced synthetic efficiency. The C−H bond of terminal alkynes (the donor alkynes) can be added to either terminal alkynes (self-coupling) or activated internal alkynes (cross-coupling) (the acceptor alkynes) in the presence of
    加成反应的发展,其中产物是反应物加上任何其他东西(仅需要催化)的简单总和,构成了提高合成效率的重要目标。在催化量的乙酸钯存在下,末端炔烃(供体炔烃)的 CH 键可以添加到末端炔烃(自偶联)或活化的内部炔烃(交叉偶联)(受体炔烃)上。富电子空间位阻配体,三(2,6-二甲氧基苯基)膦。用于交叉偶联的活化内部炔烃(受体炔烃)包括带有酯、砜和酮的炔烃。自偶联完全被交叉偶联所淹没,即使供体和受体炔烃的比例为 1:1。该反应对游离的甲醛、醇、
  • Palladium-Catalyzed Decarboxylative<i>sp</i>-<i>sp</i><sup>2</sup>Cross-Coupling Reactions of Aryl and Vinyl Halides and Triflates with α,β-Ynoic Acids using Silver Oxide
    作者:Hyunseok Kim、Phil Ho Lee
    DOI:10.1002/adsc.200900502
    日期:2009.11
    Palladium-catalyzed decarboxylative sp-sp2 cross-coupling reactions of aryl and vinyl halides and triflates with α,β-ynoic acids using silver oxide have been developed. A variety of α,β-ynoic acids were readily decarboxylated in the presence of silver oxide and then, generated in situ, silver acetylides were coupled with electrophiles in the presence of a palladium(0) catalyst under neutral conditions

  • Lanthanide-Catalyzed Reversible Alkynyl Exchange by Carbon-Carbon Single-Bond Cleavage Assisted by a Secondary Amino Group
    作者:Yinlin Shao、Fangjun Zhang、Jie Zhang、Xigeng Zhou
    DOI:10.1002/anie.201605822
    日期:2016.9.12
    Lanthanide‐catalyzed alkynyl exchange through C−C singlebond cleavage assisted by a secondary amino group is reported. A lanthanide amido complex is proposed as a key intermediate, which undergoes unprecedented reversible β‐alkynyl elimination followed by alkynyl exchange and imine reinsertion. The in situ homo‐ and cross‐dimerization of the liberated alkyne can serve as an additional driving force
    据报道,通过仲氨基辅助的CC单键裂解,镧系元素催化的炔基交换。提出了镧系酰胺酰胺配合物作为关键中间体,该中间体经历了前所未有的可逆性β-炔基消除,然后进行炔基交换和亚胺重新插入。释放的炔烃的原位均聚和交叉二聚化可作为将复分解平衡转变为完成反应的另一驱动力。该反应在形式上与常规炔烃复分解反应是互补的,并允许在操作简单的反应条件下,以中等至极好的收率将内部炔丙胺选择性转化为炔烃末端带有不同取代基的那些。
  • Ru-Catalyzed (<i>E</i>)-Specific <i>ortho</i>-C–H Alkenylation of Arenecarboxylic Acids by Coupling with Alkenyl Bromides
    作者:Zhiyong Hu、Florian Belitz、Guodong Zhang、Florian Papp、Lukas J. Gooßen
    DOI:10.1021/acs.orglett.1c00956
    日期:2021.5.7
    alkenyl bromides, (E)-configured vinyl arenes or dienes are formed exclusively. Mechanistic studies show that this selectivity is achieved because the (E)-configured alkenyl bromides undergo a smooth coupling, whereas the (Z)-isomers are rapidly eliminated with the formation of alkynes.
    在[对-异丙基)RuCl 2 ] 2的存在下,(E)-构型的烯基溴化物与芳族羧酸盐偶合形成邻-乙烯基苯甲酸。这种C–H乙烯基化无需任何活化的膦配体就可以高产率进行,并且具有出色的官能团耐受性。从烯基溴化物的常见(E / Z)混合物开始,仅形成(E)构型的乙烯基芳烃或二烯。机理研究表明,实现这种选择性的原因是,(E)-构型的烯基溴化物经历了平滑的偶联,而(Z异构体会随着炔烃的形成而迅速消除。
