In this study, The HPG@KCC-1 NP was prepared through the ringopening polymerization of glycidol on the surface of KCC-1 to form HPG@KCC-1 and then HPG@KCC-1 NPs were functionalized using chlorodiphenylphosphine and phosphine-functionalized nanoparticles (HPG@KCC-1/PPh2) as a recyclable phosphorus ligand was obtained. Also, gold (III) complex of HPG@KCC-1/PPh2 ligand (HPG@KCC-1/PPh2/Au) was prepared which used for the cyclization of propargylic amines with CO2 to provide 2-oxazolidinones. High catalytic activity and ease of recovery from the reaction mixture using filtration, and several reuse times without significant losses in performance are additional eco-friendly attributes of this catalytic system.
