  • Title: A recyclable ruthenium(II) complex supported on magnetic nanoparticles: a regioselective catalyst for alkyne-azide cycloaddition.
    Author: Wang D, Salmon L, Ruiz J, Astruc D.
    Journal: Chem Commun (Camb); 2013 Aug 11; 49(62):6956-8. PubMed ID: 23807317.
    Abstract:
    A magnetically separable ruthenium catalyst was synthesized through immobilizing a pentamethylcyclopentadienyl ruthenium complex on iron oxide nanoparticles. The catalyst is highly active and selective for the synthesis of 1,5-disubstituted 1,2,3-trizoles via cycloaddition of alkynes and organic azides and can be recycled at least 5 times.
