Application
Chloro(4-cyanophenyl)[(R)-1-[(S)-2-(dicyclohexylphosphino)ferrocenyl]ethyldicyclohexylphosphine]nickel(II) serves as a versatile and air-stable catalyst, positioned as a cost-effective alternative to palladium for driving carbon-carbon and carbon-heteroatom cross-coupling reactions. Its primary function is to enable the amination of aryl and heteroaryl halides, tosylates, bromides, sulfonates, and carbamates with ammonia, thereby facilitating the production of a diverse range of aryl and heteroaryl amines. This catalyst is also effective in monoarylation processes employing commercially available ammonia gas, ammonium salts, or ammonia stock solutions. The catalyst's ability to couple aryl chlorides with gaseous amines, presented as their hydrochloride salts, underscores its utility and flexibility in various synthetic applications.
