(5 mol %) in the presence of 2,2′‐bipyridyl (5 mol %) enables electrophilic alkenylations between easily accessible alkenyl acetates or tosylates and various functionalized aryl zinc pivalates at ambient temperature. This cobalt‐catalyzed process was further applicable to alkenyl zinc pivalates to provide substituted 1,3‐dienes.
在
2,2'-联吡啶(5 mol%)的存在下,CoBr 2(5 mol%)使得在环境温度下易于获得的
乙酸烯基酯或
甲苯磺酸酯和各种官能化的
新戊酸芳基
锌之间的亲电烯基化成为可能。这种
钴催化的方法进一步适用于
新戊酸烯基
锌,以提供取代的1,3-二烯。
