Aplicação

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.
