In Heck reactions of cyclic olefins, the products usually have aryl groups that end up at the allylic and/or homoallylic position. We herein report new selectivity that adds aryl groups to the vinylic position. Cyclic olefins of various ring size worked well. The desired isomers were produced by palladium–hydride‐catalyzed isomerization of the initial products. Thus, a specific catalyst must be used
在环烯烃的Heck反应中,产物通常具有芳基,该芳基最终在烯丙基和/或均烯丙基位置。我们在本文中报道了新的选择性,该选择性将芳基添加到乙烯基位置。各种环大小的环烯烃均能很好地发挥作用。所需的异构体是通过氢化钯催化的初始产物异构化反应制得的。因此,必须使用特定的催化剂,以使其可以在一组反应条件下进行两项工作。
