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.

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.
