three-component synthesis of propargylamine derivatives via 1,4-dihydroxyanthraquinone-copper(ii) complexes as an efficient catalyst under solvent-free conditions
نویسندگان
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.
