CuI Supported on Protonated Trititanate Nanotubes: A Reusable Catalyst for the One‐Pot Synthesis of Propargylamines via A3‐Coupling

CuI Supported on Protonated Trititanate Nanotubes: A Reusable Catalyst for the One‐Pot Synthesis... CuI catalysts supported on protonated trititanate nanotubes (CuI/HTNT) were prepared and used as catalysts for the synthesis of propargylamines via A3 (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, N2‐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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Asian Journal of Organic Chemistry Wiley

Abstract

CuI catalysts supported on protonated trititanate nanotubes (CuI/HTNT) were prepared and used as catalysts for the synthesis of propargylamines via A3 (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, N2‐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.
