A simple, and efficient nano In2O3 catalyzed one-pot three-component coupling of terminal alkyne, dichloromethane. and secondary amine has been developed for the synthesis of propargylamines under mild reaction conditions. The catalyst was recovered and reused for three times without significant loss of catalytic activity. (C) 2011 Elsevier Ltd. All rights reserved.

Propargylamines can be obtained from secondary amines and terminal alkynes in chlorinated solvents by a three‐ and two‐component synthesiscatalyzed by gold compounds and nanoparticles (Au‐NP) under mild conditions. The use of dichloromethane allows for the activation of two CCl bonds and a clean transfer of the methylene fragment to the final product. The scope of the reaction as well as the influence
