Title Study on the Baeyer-Villiger reaction of cyclic ketone with hydrogen peroxide as oxidant
Abstract
A metal tin ion-exchanged bentonite appear to be rather efficient and highly selective catalysts for the Baeyer–Villiger oxidation of 2-heptylcyclopentanone to δ-dodecalactone using aqueous hydrogen peroxide (30wt%) as a clean oxidant. With tin exchanged bentonite as heterogeneous catalyst, and the reaction time is 7 h and reaction temperature is 70℃;the mole ratio of hydrogen peroxide to 2-heptylcyclopentanone is 3，the amount of toluene is10 mL,1.50 g tin ex -changed bentonite is used as catalyst in the reaction, 0.25 g methanesulfonic acid and sodium dodecyl sulfate (SDS) are used as cocatalyst separately;the conversion is 95%,the yield rate is 81%.Via persing the reactant, we found the reaction activity of different reactant is different as well.
