The compounds were characterized by spectroscopic and elemental analyses. The synthesized NHC–Ag(I) complexes (3a–c) were tested as catalysts for the catalytic threecomponent coupling reaction of aldehyde, alkyne, and amine to propargylamines in various solvents. All complexes were active catalysts for catalytic three-component coupling reactions with good yields under neat and mild conditions (after 4 h, yields of up to 94%). |
