Herein, we introduce a new class of bench-stable -heterocyclic carbene (NHC) nickel-precatalysts for homogeneous nickel-catalysis. The nickel(II) complexes are readily activated to Ni in situ under mild conditions, via a proposed Heck-type mechanism. The precatalysts are shown to facilitate carbonyl-ene, hydroalkenylation, and amination reactions.
在此，我们介绍了一类用于均相镍催化的新型台架稳定的氮杂环卡宾（NHC）镍预催化剂。通过一种提出的Heck型机理，镍（II）配合物在温和条件下易于原位活化成镍。这些预催化剂被证明能促进羰基烯反应、氢烯基化反应和胺化反应。
