Room-temperature tandem conversion of cyclic alkenes into 1,2-diols using molecular oxygen and β-MnO2 heterogeneous catalyst

Tandem conversion of cyclohexene into 1,2-cycloheanediol was attained by applying the generated by-product carboxylic acid as catalyst 2, realizing the effective utilization of isobutyric acid, shortening reaction time, and saving energy consumption.
