Nickel
Nickel catalysis plays a central role in many synthetic transformations ranging from cross coupling reactions in which carbon-carbon bonds are formed to the reduction of electron rich carbon bonds with raney nickel catalysts. Sigma-Aldrich provides an extensive suite of such nickel catalysts. These nickel catalysts span a range of oxidation states: Nickel (0), nickel (II), nickel (III) and nickel (IV). The types of Ni catalysts available for immediate purchase are aluminum nickel (Al Ni) alloys, ammonium nickel hydrates, Ni COD, Ni halides (chlorides, bromides, fluorides and iodides), Ni cyclopentadienyls, nickel metal, nickel acacs, and Raney Nickel catalysts that are products of W.R. Grace and Company.

Regardless of the application, there is an extensive and high-purity selection of Ni catalysts available in the Sigma-Aldrich product portfolio.
