애플리케이션

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

The Engle lab strives to invent novel catalytic alkene and alkyne functionalization methods to expedite organic synthesis. These transformations offer a powerful platform for conversion of simple, abundant, and planar starting materials into densely functionalized, stereochemically complex products in a single step. To this end, the Engle lab has developed various substrate directivity strategies in which native functional groups can be temporarily masked with auxiliaries that are capable of reversibly binding the metal catalyst, thereby enhancing kinetic reactivity, suppressing unwanted side reactions, and facilitating high selectivity. The Engle lab works with us to make synthetically enabling directing groups, catalysts, and ligands readily available to the synthetic community for reaction discovery and small-molecule synthesis.
