Application

The following Ni-complex is an air-stable precatalyst for various Ni-catalyzed reactions which normally require Ni(cod)2, however, this precatalyst will not require any glovebox or schlenk techniques that must be followed with Ni(cod)2. Rates are enhanced and selectivity is maintained when compared to the same reaction with Ni(cod)2.

Tremendous advances have been made in nickel catalysis over the past decade. Several key properties of nickel, such as facile oxidative addition and ready access to multiple oxidation states, have allowed the development of a broad range of innovative reactions.

Articles

The Jamison group has developed a library of bench-stable phosphine-containing nickel(II) precatalysts that are converted into active catalysts in situ.

Nickel transition metal and its complexes can be used as a catalyst in many synthetic transformations, like oxidative addition, C-H activation, reductive elimination, oxidative cyclization, oligomerization, and in cross-coupling reactions.

Related Content

Research in the Jamison group is centered on the development of new reactions and technologies for organic synthesis. Towards these themes, the group has pioneered a number of air-stable nickel precatalysts supported by phosphines and N-heterocyclic carbenes that are readily converted to the active catalyst in situ.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
