Beschreibung

Anwendung

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.
