Unsupported copper nanoparticles in the 1,3-dipolar cycloaddition of terminal alkynes and azides

Alonso Valdés, Francisco; Moglie, Yanina; Radivoy, Gabriel; Yus Astiz, Miguel

Readily prepared copper nanoparticles were found to catalyse the 1,3-dipolar cycloaddition of azides and alkynes up to rates comparable to those of microwave chemistry. Both the preparation of the nanoparticles and the click reaction are carried out under mild conditions, in short reaction times and...
