Magnetic-MOF Zinc nanocatalyst in DESs Solvent: a sustainable route for 2,4-Disubstituted Quinoline synthesis

Growing interest in environmentally friendly procedures in organic synthesis has motivated the discovery of greener catalytic systems. In this present work, an efficient and environmentally friendly synthesis method of 2,4-diaryl quinolines has been introduced under recyclable magnetic metal-organic framework (Magnetic-MOF) zinc nanocatalysis in deep eutectic solvents (DESs). The recyclable catalyst, MNPs@Cellulose/Zn-MOF, was synthesized and fully characterized, displaying great activity, excellent selectivity, and outstanding reusability under mild reaction conditions. The use of DESs as green solvents has enhanced the catalytic activity and avoided the use of harmful solvents. Notably, the magnetic nature of the catalyst facilitates the recovery and reuse of the catalyst up to eight times without significant loss in activity. The paper identifies the potential of Magnetic-MOF nanocatalysts in driving green synthetic procedures and encouraging environmentally friendly catalytic reactions.
