was found to be a highly effective catalyst for the three-componentcoupling reactions of aldehydes, alkynes, and amines (A3-coupling) via C−H activation. The reactions could be applied to both aromatic and aliphatic aldehydes and alkynes. Nearly quantitative yields of the desired products were obtained in most cases. No cocatalyst or activator is required, and water is the only byproduct in the reactions

A tri‐umph in many respects: The iron‐catalyzed ligand‐free, one‐pot three‐componentcoupling reactions of aldehydes, terminal alkynes, and amines in the presence of 4 A molecular sieves yields the corresponding propargylamines in good to excellent yields, displays a broad substrate scope, and is economical and environmentally friendly (see scheme).
