Introduction of Terminal Azide and Alkyne Functionalities in Polymers

“Click” chemistry, and the copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) in particular, is a powerful new synthetic tool in polymer chemistry and material science.

Hydroazidation Catalyst

The chemistry of organoazides is exceedingly rich, since the azide functionality reacts with electrophiles, nucleophiles, and dipolarophiles, with or without the extrusion of dinitrogen. Common place transformation such as Staudinger reductions or ligations, Cu(I)-catalyzed Huisgen cycloadditions (of the “click” reaction family), Curtius or Schmidt rearrangents, nitrene reactions, or imine formation via aza-Wittig reactions all necessitate organoazide precursors or intermediates

Organic Azides and Azide Sources

Since the preparation of the first organic azide, phenyl azide, by Peter Griess in 1864 this energy-rich and versatile class of compounds has enjoyed considerable interest.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
