    容易获得的镍络合物作为烯烃和炔烃分子间加氢胺化的催化剂†
    摘要:
    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。

  • Enamines as Surrogates of Alkene Carbanions for the Reductive Alkenylation of Secondary Amides: An Approach to Allylamines
    作者:Ai-E Wang、Cun-Cun Yu、Ting-Ting Chen、Yong-Peng Liu、Pei-Qiang Huang
    DOI:10.1021/acs.orglett.7b03943
    日期:2018.2.16
    A new strategy to construct allylamines through reductive alkenylation of secondary amides with enamines is reported. The method features the use of trifluoromethanesulfonic anhydride as an activation reagent of amides, and enamines as unconventional alkenylation reagents. In this manner, enamines serve as surrogates of alkene carbanions instead of the classical enolates equivalents. A possible mechanism
