| چکیده | ||
| Highly active Cu (II) complex with 1,4-dihydroxy anthraquinone as a cheap and accessable ligand could be used as a catalyst for the preparation of structurally different propargylamines from a one-pot, three-component reaction of terminal alkynes, aldehydes, and secondary amines with high yields under solvent-free conditions. The 1,4-dihydroxy anthraquinone is a very efficient Cu(II) scavenger that is able to catalyse the A3-coupling reaction without pre synthesis of the catalyst. | ||
