| 2-乙炔苯甲酰胺 | 2-ethynylbenzamide | 1207252-50-3 | C9H7NO | 145.161 |
Heterogeneous tandem cyclization of 2-alkynylbenzamides with ammonium acetate is achieved in acetonitrile at 85 °C using a magnetic nanoparticles-immobilized bipy-gold(III) complex and AgSbF6 as catalysts to afford a variety of 1-aminoisoquinoline derivatives in moderate to high yields. This heterogeneous gold catalyst can be easily recovered from the reaction mixture by simply applying an external magnetic field and can be recycled at least seven times without any apparent loss of catalytic activity.
