CuI catalysts supported on protonated trititanate nanotubes (CuI/HTNT) were prepared and used as catalysts for the synthesis of propargylamines via A 3 (aldehyde, amine and acetylene) coupling under solvent‐free conditions. The results revealed that the CuI/HTNT with 5 wt % CuI had the best catalytic activity. The protocol provides access to a wide range of propargylamines in excellent yields (up to 98 %). The prepared catalysts were characterized by TEM, XRD, N 2 ‐adsorption desorption, EDS and ICP‐MS analysis. The catalyst can be recovered by centrifugation and reused in further catalytic reactions, its activity remaining largely unchanged for five successive runs.
