    丁烯酸二烯二醇锂的烷基化。烷基化剂的结构和离去基团的区域选择性作用
    摘要:
    丁-2-烯酸1和2被烷基卤化物烷基化的区域选择性在很大程度上取决于亲电试剂的反应性。饱和烷基卤化物的α选择性高,而高反应性烯丙基卤和苄基卤的α选择性差。对于反应性烷基化卤化物,选择性部分地由二烯二醇的离子对聚集体决定。正在进行的反应中生成的溴化锂和羧酸盐对区域选择性产生相反的影响。

    A new type of intermolecular alkylative olefination of unactivated olefins and alkyl halides has been realized for the first time. This copper-promoted Heck-type reaction employs a directing-group strategy to efficiently produce the coupled alkyl olefin products with excellent regio- and stereoselectivity.

  • A Light/Ketone/Copper System for Carboxylation of Allylic C−H Bonds of Alkenes with CO<sub>2</sub>
    作者:Naoki Ishida、Yusuke Masuda、Sho Uemoto、Masahiro Murakami
    DOI:10.1002/chem.201600682
    日期:2016.5.4
    carboxylation reaction of allylic C−H bonds of simple alkenes with CO2 is prompted by means of a ketone and a copper complex. The unique carboxylation reaction proceeds through a sequence of an endergonic photoreaction of ketones with alkenes forming homoallyl alcohol intermediates and a thermal copper‐catalyzed allyl transfer reaction from the homoallyl alcohols to CO2 through C−C bond cleavage.
