Propargylamines are synthesized via metal-free activation of the C–halogen bond of dihalomethanes and the C–H bond of terminal alkynes in a three-componentcoupling without catalyst or additional base and under mild reaction conditions. The dihalomethanes are used both as solvents as well as precursors for the methylene fragment (C1) in the final product. The scope of the reaction and the influence

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.
