The palladium-catalyzed chemoselective mono-amination of dichlorobenzenes was reported in this paper. Under the suitable conditions, allreactions involving the threeisomers of dichlorobenzenes with various secondary and primary amines in the presence of a well-defined N-heterocyclic carbene-palladium(II)-2-methyl-4,5-dihydrooxazole complex, gave the desired mono-aminated products in moderate to high
