Propargylamines are a versatile class of compounds which find broad application in many
fields of chemistry. This review aims to describe the different strategies developed so far for …

A3 coupling is one of the few transition‐metal catalyzed carbon‐carbon bond forming
reactions that have been established as a most direct, efficient and atom‐economical …

The multicomponent reaction of aldehydes, amines, and alkynes, known as A3 coupling,
yields propargylamines, a valuable organic scaffold, and has received significant interest …

Here we prepared a highly efficient and reusable catalyst by a step-by-step postsynthesis
modification of UiO-66-NH2 metal–organic frameworks (MOFs) with nitrogen-rich organic …

Novel copper nanoparticles supported on starch micro particles (CuNPs@ MS) were
prepared successfully and characterized by SEM, EDX, TEM, SAED, TGA, XPS, and XRD …

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 …

Halloysite nanoclays (HNTs) were functionalized with (3-chloropropyl) trimethoxysilan and
subsequently reacted with thiosemicarbazide and furfural to furnish furfural imine …

A CuO nanoparticles (CuO NPs)/graphene nanosheet (GNS) hybrid was prepared by a very
simple method and employed as a nanocatalyst (CuO/GNS) for base free coupling …

In this paper, Zn (II) anchored onto the magnetic natural hydroxyapatite (ZnII/HAP/Fe3O4),
as a new, versatile and magnetically recoverable catalyst, was prepared and characterized …

The present work deals with the investigation and catalytic activity analysis of copper
nanoparticles (CuNPs) supported on a zinc oxide–polythiophene (ZnO–PTh) …
