Chemical modification of poly(vinyl chloride) (PVC) by the replacement of chlorine atom presents a considerable interest in this work. In the first phase, PVC was partially azided with a sodium azide. Click-chemistry based on Copper (I)-catalyzed Hui

In order to prepare substituted polymers bearing functional groups to chelate metals for their application in extraction and/or depollution applications, Merrifield polymer was transformed into the known azidomethyl polystyrene. Click-chemistry based

In order to remove metals (Zn & Mg) located in wastewater, a new series of clickable polystyrene Merrifield grafted with azide and alkynes were synthesized and implicated in this domain. In a first step, we transformed the polystyrene Merrifield into

In order to find new molecules with cytotoxic activity against cancer cells, we prepared bis-akyne amides derived from propiolic acid. The bis-alkynes were then transformed in their mono-1,2,3-triazole analogs onto the amide side, due to its greater

We propose in this work to compare three approaches using 4-azidoaniline combined with “click” chemistry and electrochemistry to anchor ferrocene moieties at glassy carbon surfaces. The immobilisation of a newly synthesised molecule, 4-(4-ferroce

Terminal alkynes substituted by a carbonyl-type electron-withdrawing group have been found to undergo Huisgen’s cycloaddition with azides at room temperature in a solvent-free manner; without a need of either heating or catalysis. Metallic salts, o

Best of both worlds, molecules bearing two alkyne groups, activated and unactivated, can selectively react on the activated one in a copper-free version of Huisgen’s reaction to form a first triazole ring, with a good selectivity toward the 1,4-iso

A new catalytic system based on copper(I)-doped Wyoming’s montmorillonite was elaborated. This system was studied and was found to catalyze the formation of 1,4-disubstituted 1,2,3-triazoles when starting from azides and alkynes. It was used for th

Bisalkynes bearing an activated and an unactivated alkyne group react site-selectively in a copper-free 1,3-dipolar cycloaddition with azides to give a mixture 1,4- and 1,5-isomers (III) and (IV).
