摘要：
Aromatic imines derived in situ from aryl aldehydes and aryl amines undergo smoothly, cyclization with alkynes on the surface of montmorillonite clay impregnated with copper(I) bromide under solvent-free conditions to produce 2,4-disubstituted quinolines in high yields with excellent selectivity. The reaction rates and yields are significantly improved by employing microwave irradiation.
