High Surface Area CeO2 Promoted Suzuki-Miyaura Cross-Coupling of Arylboronic Acids and Aryl Iodides

Abstract

High surface area cerium oxide (240 m2/g) efficiently promoted the Suzuki-Miyaura cross-coupling of aryl iodides with arylboronic acids, in the absence of palladium or any other transition metal catalyst. Excellent selectivity towards the cross-coupling product was observed. Cerium oxide could be recovered and reused at least three times without any loss of activity.
