two recently developed nickel-catalyzed coupling reactions of alkenes, aldehydes, and silyl triflates is presented. These reactions provide either allylic alcohol or homoallylic alcohol derivatives selectively, depending on the ligand employed. These processes are believed to be mechanistically distinct from Lewis acid-catalyzed carbonyl-ene reactions, and several lines of evidence supporting this hypothesis
介绍了最近开发的烯烃、醛和甲硅烷基三氟甲磺酸酯的两个最近开发的镍催化偶联反应的完整说明。这些反应选择性地提供烯丙醇或高烯丙醇衍生物,这取决于所采用的配体。这些过程被认为在机械上不同于路易斯酸催化的羰基 - 烯反应,并且讨论了支持这一假设的几条证据。
