Oxidative esterification of alcohols by a single-side organically decorated Anderson-type chrome-based catalyst
Résumé
The exploration of non-noble metal systems in direct esterification of alcohols faces great challenges. Here, a new system using [N(C4H9)4]3[CrMo6O18(OH)3C(OCH2)3CH2OH}] as catalyst to realize the efficient transformation from alcohols to esters without organic ligands. A variety of alcohols are tolerated in this system. The chrome- based catalyst can be recycled several times and still keep the original configuration and catalytic activity. We also propose the reasonable catalytic mechanism and prove the potential for industrial applications.
