trisubstituted styrene derivatives were reacted to give the desired diarylalkanes within less than an hour at room temperature in the presence of 2.5 mol % of Ca(NTf2)2/Bu4NPF6 (see scheme). Additionally, the highly reactive calcium catalyst was successfully applied for the hydroarylation of dienes and even trisubstituted olefins.
钙催化剂的发展:在室温下,在2.5 mol%Ca(NTf 2)2存在下,在不到一小时的时间内,使各种贫电子,富电子和三取代的
苯乙烯衍
生物反应生成所需的二芳基
烷烃/ Bu 4 NPF 6(请参阅方案)。另外,高反应性
钙催化剂已成功地用于二烯甚至三取代烯烃的加氢芳基化反应。
