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. Tetramethylguanidine
A 1D Cu(I)-coordination polymer [(CuL1)(CuBr2), 1] carrying external copper bromide moieties was synthesized. The outer-hanging [CuBr2]− moiety is attached to the 1D Cu(I)-CP backbone via a Cu⋯Cu bonding interaction, which makes it look like a coordination polymer supported CuBr2 species. 1 exhibits excellent multifunctional catalytic activity for phenol acetylation, A3-coupling (aldehyde–alkyne–amine)

of highly efficientcatalyst [Cu(μ − I)2Cu}(PPh3)4] for the synthesis of biologically and pharmaceutically important propargylamine derivatives through microwave assisted A3-coupling reaction is described. The A3-coupling reaction performed under microwave conditions with a catalyst loading of 0.1 mol% produced propargylamines in almost quantitative isolated yields. Most of the reactions were completed

A MOF-supported Cu(I) catalyst bearing N,O-chelating ligand was prepared through postsynthetic modification of IRMOF-3 and used as an efficient heterogeneous catalyst for three-componentcoupling reaction of aldehyde, alkyne, and amine. The catalyst exhibited both high catalytic activity and stability for the reaction and the framework of Cu(I) catalyst was mainly maintained after the catalyst was
A new, heterogeneous, 4 Å molecular sieve-supported copper(II) catalyst was developed and was used successfully in the A3 coupling of alkynes, aldehydes and amines under simple reaction conditions.
