Abstract
An efficient copper-based catalytic system (Cu/PTABS) enables an amination of a chloroheteroarenes at ambient temperature in water as the sole reaction solvent. A wide variety of chloroheteroarenes could be coupled efficiently with primary and secondary amines as well as selected amino acid esters under mild reaction conditions.
