Copper(0)-Induced Deselenative Insertion of N,N-Disubstituted Selenoamides into Acetylenic C−H Bond Leading to Propargylamines
摘要:
Upon heating at 110 degrees C in the presence of copper(0) powder, terminal acetylenes undergo a novel deselenative C-H bond insertion reaction of N,N-substituted selenoamides, affording the corresponding propargylamines in good to excellent yields, selectively.

An efficient heterogeneous lead sulfide-gold catalyst has been successfully developed for the synthesis of propargylic amines via a three-componentcoupling reaction of aldehyde, amine and alkyne in water. The process is simple and applicable to a diverse range of aromatic and aliphatic aldehydes, amines and alkynes. Furthermore, the catalyst is stable to air and water, and can be easily recovered

expeditious and solvent‐free synthesis of propargylamines via A3‐coupling of aldehydes, alkynes, and amines has been proposed. A wide range of aldehydes, alkynes and amine substrates undergo A3‐coupling to produce propargylamines in good to excellent yields with good functional tolerance, such as that towards alkoxy, hydroxy, C‐X (X = F, Cl, Br) as well as amide and C=C bonds. Furthermore, the catalyst could

Cu nanoparticles were deposited on nanoporous carbon, MOF-5-C, which was fabricated by direct carbonization of MOF-5 without any additional carbon sources. The as-obtained catalyst ([email protected]) exhibited high catalytic activity due to the high surface area as well as hierarchical pores of MOF-5-C, and the synergetic interaction between the metal nanoparticles and support.
