摘要：

A general synthetic route to the first Xantphos nickel alkyne and alkene complexes has been discovered. Various Ni pi-complexes were prepared and characterized. NMR experiments indicate benzonitrile undergoes ligand exchange with a Xantphos ligand of (Xant)(2)Ni, a compound that was previously believed to be unreactive. The Ni pi-complexes were also shown to be catalytically competent in cross coupling and cycloaddition reactions. (Xant)(2)Ni is also catalytically active for these reactions when activated by a nitrile or coordinating solvent.
