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).
