An efficient and straightforward copper-catalyzed method allowing vinylation of N-nucleophiles with various substituted (E)-vinyl bromides under palladium-free and ligand-free conditions has taken a high yield (up to 95%). Noteworthy is that the double-bond geometry of these vinyl halides was retained with our protocol.
一种高效且直接的铜催化方法可以在无钯和无配体条件下,以高产率(高达95%)实现各种取代的(E)-乙烯基溴与N-亲核试剂的乙烯基化反应。值得注意的是,我们的方案保留了这些乙烯基卤化物的双键几何结构。
