Abstract

The 1,2-diol motif is frequently found in biomass-derived compounds; thus, its direct and selective C–C bond cleavage is crucial for broadening the utility of biomass resources. In this paper, we report that CeO2 showed high catalytic activity for the C–C bond cleavage of 1,2-diols. Moreover, Mn-doped CeO2 demonstrated higher activity than pristine CeO2, enabling the efficient conversion of 1,2-diols into the corresponding carbonyl compounds in high yields. Mechanistic investigations revealed that the redox and surface basic properties of CeO2 was the key for facilitating catalytic C–C bond cleavage. The high reusability of the Mn-doped CeO2 catalyst underscores its potential for practical and sustainable synthetic applications.
