Ligand and additive free aerobic synthesis of diynes using Pd–CuFe2O4 magnetic nanoparticles as an efficient reusable catalyst

Author affiliations

Abstract

Herein, we present the synthesis of Pd–CuFe2O4 magnetic nanoparticles as an efficient and recyclable catalyst for the oxidative homocoupling of various terminal alkynes to form symmetric 1,3-diynes. The catalyst was found to be effective with very low palladium loading. The protocol has the advantages of easy synthesis of the catalyst, mild reaction conditions, short reaction times, excellent product yields and enhanced recyclability of the catalyst.
