Direct alkenylation of a variety of alcohols with vinylboronic acids has been accomplished using the air‐stable calcium(II) complex Ca(NTf2)2 under mild conditions with short reaction times. For reluctant transformations, an ammonium salt was used as an additive to circumvent the reactivity issue.
使用空气稳定的钙(II)络合物Ca(NTf 2)2可以在温和的条件下以较短的反应时间完成各种醇与乙烯基硼酸的直接烯基化反应。对于勉强的转化,使用铵盐作为添加剂来规避反应性问题。
