Synthesis of copper catalysts for click chemistry from distillery wastewater using magnetically recoverable bionanoparticles

Magnetically recoverable ruthenium catalysts in organic synthesis.

Magnetically recyclable catalysts with magnetic nanoparticles (MNPs) are becoming a major trend towards sustainable catalysts. In this area, recyclable supported ruthenium complexes and ruthenium nanoparticles occupy a key place and present great advantages compared to classic catalysts. In this micro-review, attention is focused on the fabrication of MNP-supported ruthenium catalysts and their...

One-pot synthesis of xanthones using a novel copper-based magnetically recoverable nanocatalyst

A versatile and straightforward strategy to construct a xanthone skeleton via an intermolecular catalytic coupling of 2-substituted benzaldehydes and a wide range of phenols has been developed. For this purpose, a novel and magnetically recoverable catalyst consisting of copper nanoparticles on nanosized silica coated maghemite in absence of ligand is presented. The reaction proceeds smoothly w...

Thiacycloalkynes for Copper-Free Click Chemistry**

Bioorthogonal chemistry enables the interrogation of biomolecules and physiological processes that are inaccessible by using conventional research tools. A common experimental protocol starts by labeling a target biomolecule in cells or live organisms with a bioorthogonal functional group. Then, a probe molecule bearing complementary functionality is added to the system and the ensuing bioortho...

Reusable and highly active supported copper(I)-NHC catalysts for Click chemistry.

Immobilised [Cu(NHC)] catalysts are reported for the preparation of 1,2,3-triazoles. In addition to showing outstanding catalytic activity, the catalyst systems are easy to prepare and can be recycled many times.
