| Résumé |
|
A convenient preparation of graphite-supported ultra-small copper nanoparticles (Cu NPs) has been developed. Ultra-small Cu NPs, generated by reduction of Cu(OAc)(2) with H-2, were well dispersed onto the graphite support and possess a very narrow distribution in size, ranging from 1.6 to 2.6 nm. The catalytic activity of these ultra-small graphite-supported Cu NPs was evaluated for the Meerwein arylation of pyrroles and the multicomponent synthesis of 1,2,3-triazoles via click reaction.
