liquid phase oxidation of saturated nitrogen-containing heterocyclics over modified MCM-41 moleuclar sieves

摘要

For the first time, the liquid phase oxidation reactions of saturated N-heterocyclics like piperidine and pyrrolidine to piperidone and pyrrolidone have been carried out over modified MCM-41 moleuclar sieves with 30-55% yield and>80% selectivity.
