Özet

The synthesis and characterization of [PdCl2(N-heterocyclic carbene)(2)] (2, 3), an air and moisture-stable complexes are reported. Amination of aryl halides in 1-methy-3-butyl-imidazolidinium tetrafluoroborate in the presence of palladium-carbene complexes as catalysts are described. Aryl chlorides undergo smooth nucleophilic substitution reactions with primary amines in ionic liquid to afford the corresponding arylamines in excellent yields under mild conditions.
