quantitative amount of metal oxidants. Although transfer hydrogenation and C-H alkenylation are two important areas that evolved independently, we herein report the first iridium-catalyzed cross-coupling reactions of alkenes by integration of directed C(alkenyl)-H alkenylation and transfer hydrogenation to obviate the usage of a metal oxidant, employing a hydrogen acceptor such as inexpensive chloranil.
已经证明,使用一定量的金属氧化剂,烯烃的一系列Ru-,Rh-或Pd催化的乙烯基CH / CH交叉偶联反应可提供1,3-二烯。尽管转移氢化和CH烯基化是两个独立发生的重要领域,但我们在本文中报道了通过直接C(烯基)-H烯基化和转移加氢的整合来实现铱的烯烃催化的交叉偶联反应,从而避免了金属氧化剂的使用,使用氢受体,例如廉价的氯乙腈。
