The copper-catalyzed regioselective intermolecular hydroamination of terminal alkyneswith amines was accomplished. The reaction was catalyzed by copper nanoparticles supported onmontmorillonite K10 (CuNPs/MK10) and afforded the desired imines in good conversions. Then,imines were transformed into the corresponding amines after treatment with NaBH3CN. The catalyst could be recovered and reutilized in several cycles.
