The oxidative condensation of furfural with aliphatic alcohols catalyzed by the supported Co_xO_y–N catalysts is developed in the presence of molecular oxygen. For the oxidative condensation process of furfural, n-propanol and dioxygen, a 75.1% conversion of furfural and 92.8% selectivity of 3-(furan-2-yl-)-2-methylacryaldehyde was obtained when the Co_xO_y–N@K-10 and cesium carbonate was employed as catalytic system. Moreover, the reaction conditions were optimized and the oxidative condensation of furfural with different aliphatic alcohols was also investigated. The synergistic effect between the Co_xO_y–N@K-10 and basic additive was considered to be responsible for this cascade process. Furthermore, a possible reaction mechanism is proposed for oxidative condensation of furfural–n-propanol–O₂ (FPO) system.
