1,5,7‐Triazabicyclo[4.4.0]dec‐5‐ene was immobilized on magnetic γ‐Fe 2 O 3 nanoparticles as a magnetic nanocatalyst. The nanoparticle reagent was obtained with good loading levels and has been successfully used for the efficient and selective synthesis of organic carbonates by the direct condensation of alcohols and diethyl carbonate. The catalyst is quantitatively recovered by an external magnet and can be reused for six cycles with almost consistent activity.
