Abstract
An efficient protocol has been established for the synthesis of conjugated ynones via addition of terminal alkynes to aromatic nitriles, which is catalyzed by novel divalent lanthanide amide complexes. All the reactions gave the products in good to excellent yields at room temperature under solvent-free conditions without any additives. The novel lanthanide amide catalysts were also synthesized and structurally characterized for the first time.
