Oxidative cross-coupling reaction of catechols with active methylene compounds in an aqueous medium using an AlPO4-supported Ru catalyst†
Abstract
A green oxidative coupling reaction of catechols with active methylene compounds was achieved using an AlPO4-supported Ru catalyst, where O2 and H2O were used as the ideal oxidant and solvent, respectively. The catalyst is easily separable, reusable and applicable for gram-scale syntheses.
