Application

Ni(COD)(DQ), as shown by the Engle lab, is an air- and thermally stable Ni(0) precatalyst. This 18-electron complex has a unique stability profile allowing for easy reaction setup outside an inert atmosphere. Transformations such as the Suzuki-Miyaura coupling, borylation of aryl halides, and alkene hydroarylation have been demonstrated.

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...
