Covalently anchored ruthenium-phosphine complex on mesoporous organosilica: Catalytic applications in hydrogenation reactions

► Heterogenization of PPh3 η6-p-cymene ruthenium complex on mesoporous silica. ► Catalytic applications in selective alkene hydrogenation reactions. ► PMO supported catalyst showed high activity and stability than MCM-41 silica. ► Hydrophobicity in PMO enhances the stability of organometallic complexes.
