Mechanism of Brønsted acid-catalyzed conversion of carbohydrates

Potential Brønsted acid-catalyzed glucose and fructose conversion routes to levulinic acid have been studied by DFT calculations. The most favorable mechanisms for sugar transformations initiated by protonation of different OH groups are identified. It is demonstrated that the differences in the rea...
