A versatile new monomer family: functionalized 4-vinyl-1,2,3-triazoles via click chemistry.
نویسندگان
چکیده
Using facile, highly modular synthetic approaches, a new monomer family based on a 1,2,3-triazole-4-vinyl building block has been prepared, and various functional derivatives have been obtained. Subsequent homo- and copolymerization of these novel functionalized monomers gives polymeric materials with unique physical properties, combining many attractive features of more traditional monomers, such as styrene, vinylpyridine, and meth/acrylates.

The synthesis of isomeric, functionalized 4-vinyl-1,2,3-triazole and 5-vinyl-1,2,3-triazole monomers is demonstrated using heterogeneous copper (copper-in-charcoal)-catalyzed azide-alkyne cycloaddition (CuAAC) or homogeneous ruthenium (Ru)-catalyzed azide-alkyne cycloadditions (RuAAC) “click” protocols. These reactions are regiospecific, exclusively forming 1,4and 1,5-disubstituted triazoles as...

In this work, the SBA-15-supported dithizone-copper(I) [SBA-15-dtz–Cu(I)] complex as a new heterogeneous catalyst is prepared for the first time. The catalyst prepared is characterized by the FT-IR spectroscopy, SEM, and ICP techniques. This reusable heterogeneous catalyst can be used in the click reactions for the green and facile synthesis of 1,4-disubstituted 1,2,3-triazolesvia a on...

In this work, copper(II) heterogeneous nanocatalyst supported on modified AlPO4 (Cu(II)-DA@Nano AlPO4) was used for the synthesis of some biological active heterocyclic molecules, particularly for the efficient conversion of a wide range of non-activated terminal alkynes to β-hydroxy 1,4-disubstituted 1,2,3-triazolethrough a three-component “click” reaction at room temperature in water. The reg...
