We report that Ni(COD)(DQ) (COD=1,5-cyclooctadiene, DQ=duroquinone), an air-stable 18-electron complex originally described by Schrauzer in 1962, is a competent precatalyst for a variety of nickel-catalyzed synthetic methods from the literature. Due to its apparent stability, use of Ni(COD)(DQ) as a precatalyst allows reactions to be conveniently performed without use of an inert-atmosphere glovebox, as demonstrated across several case studies.
我们报告称，Ni(COD)(DQ)（COD=1,5-环辛二烯，DQ=二醌），一种由 Schrauzer 于 1962 年首次描述的空气稳定的 18 电子配合物，是文献中多种镍催化合成方法的有效前催化剂。由于其明显的稳定性，Ni(COD)(DQ)作为前催化剂的使用允许在无需使用惰性气氛手套箱的情况下方便地进行反应，这在几个案例研究中得到了证明。
