alkenyldiazo compounds and unsaturated substrates. The process represents a new CC bond‐formation reaction in which alkenes, alkynes, and arenes are active reagents for the Cγ‐allylation, ‐allenylation, and ‐arylation, respectively, of alkenyldiazo substrates (see scheme). The reactivity pattern is likely to rely on the formation of a highly electrophilic alkenylgold carbenoid, which may be involved in a
他们击中了金子!在烯基重氮化合物和不饱和底物的金催化反应中观察到新的反应模式。该过程代表了一个新的CC键形成反应,其中烯烃,炔烃和芳烃分别是烯基重氮底物Cγ烯丙基化,烯丙基化和芳基化的活性试剂(参见方案)。反应模式可能取决于高度亲电的链烯基金类胡萝卜素的形成,这可能与碳正离子型机制有关。
