Oxidation of adamantanone and norcamphor over tin containing mesoporous molecular sieves
Original language description
Oxidation of adamantanone and norcamphor in Beyer-Villiger reaction, by hydrogen peroxide as oxidating agent using mesoporous molecular sieves as catalysts with tin in structure, was investigated in a liquid phase. Different procedures for synthesis of catalysts to study the influence of synthesis procedures and the dependence of tin content were used. It was shown that all types of catalysts, both (Sn)MCM-41 exhibited conversions of adamantanone between 42-90% and of norcamphor between 32-73% while (Sn)MCM-48 exhibited conversions of adamantanone between 51-100% and conversions of norcamphor between 53-86%. In all reactions the selectivities to desired lactones were almost 100%. No direct relationship has been found between the conversions of individual ketones and bulk concentrations of tin in both (Sn)MCM-41 and (Sn)MCM-48. The Lewis sites accessible for pyridine measured by FTIR spectroscopy do not probably participate in Baeyer-Villiger reaction to the same extent.
