bond formation reactions using alkynes. Propargylic amines are synthetically versatile intermediates for the preparation of many nitrogen‐containing biologically active motifs. Herein, a 15 mol% Ni(py)4Cl2/bipyridine‐catalyzed three‐component coupling reaction of alkynes, halomethane and amines through C―H and C―halogen activation was developed for the facilesynthesis of propargylic amines.

A simple, efficient and highly functional group compatible method for the synthesis of propargylamines from terminal alkynes, dichloromethane and tertiary amines using silver catalysts has been developed.

Efficient iron(iii)-catalyzed three-component coupling reaction of alkynes, CH2Cl2 and amines to propargylamines
An iron(III)-catalyzed three-component coupling reaction of alkynes, CH(2)Cl(2) and amines was developed for facile synthesis of propargylamines. Preliminary mechanism investigation using in situ FT-IR reveals that the crucial Fe-acetylide intermediate could be formed through C-H bond activation of alkynes thanks to cooperative effect of FeCl(3) and 1,1,3,3-tetramethylguanidine.

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
