A recyclable ruthenium(Ⅱ) complex supported on magnetic nanoparticles: a regioselective catalyst for alkyne-azide cycloadditiont

摘要

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.
