When CuAAC 'Click Chemistry' goes heterogeneous
Within the green chemistry context, heterogeneous catalysis is more and more applied to organic synthesis. The well known ‘click chemistry’ and especially its flagship, the copper-catalyzed azide–alkyne cycloaddition reaction (CuAAC), is now catch up by such heterogenisation process and copper ions or metals have been grafted or deposited on or into various solids, such as (bio)polymers, charcoal, silica, zeolites, POM or MOF.

Metabolic labelling of cancer cells with glycodendrimers stimulate immune-mediated cytotoxicity
Combining glycometabolism and bio-orthogonal chemistry to label cells with antigenic glycodendrimers lead to the activation of immune response against cancer cells.

Prolinamide plays a key role in promoting copper-catalyzed cycloaddition of azides and alkynes in aqueous media via unprecedented metallacycle intermediates
Room temperature copper-catalyzed cycloaddition of azides and alkynes (CuAAC) proceeds in the presence of a prolinamide ligand in aqueous media via unique metallacycles.

About this collection
This cross-journal collection is dedicated to bioorthogonal and click chemistry, in honour of the 2022 Nobel Prize in Chemistry. Click chemistry is best represented by its most elegant and widespread example, the copper catalysed azide-alkyne cycloaddition (CuAAC). Bioorthogonal reactions are click reactions that take place without disrupting the normal chemistry of the cell, inside living organisms, and these are now used to track biological processes. The scope of this collection highlights key historic works in bioorthogonal and click chemistry alongside showcasing recent developments and applications of these now ubiquitous techniques.
