first single‐operation, highly selective intermolecular tail‐to‐tail hetero‐hydroalkenylation from two readily available monosubstituted alkenes is described (see scheme; IPr=1,3‐Bis(2,6‐di‐isopropylphenyl)imidazol‐2‐ylidene). The reaction is catalyzed by the proposed [(IPr)NiH]OTf species. The method allows the use of more common and structurally diverse α olefins as substrates, which were previously
使头或它的尾巴:第一单操作中,高选择性的分子间尾对尾杂hydroalkenylation从两个容易获得单取代的烯烃中描述(参见方案; IPR = 1,3-双(2,6-二-异丙基苯基)咪唑-2-亚丙基。该反应由提出的[(IPr)NiH] OTf物种催化。该方法允许使用更常见且结构上不同的α-烯烃作为底物,其先前与已知方法不相容。
