Tran, Van T. published the artcileNi(COD)(DQ): An Air-Stable 18-Electron Nickel(0)-Olefin Precatalyst, Formula: C27H39ClN2, the publication is Angewandte Chemie, International Edition (2020), 59(19), 7409-7413, database is CAplus and MEDLINE.
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-atm. glovebox, as demonstrated across several case studies.
