Aldehydes And Ketones

Ceria (CeO2) nanoparticles (NPs) have been produced from cerium nitrate and walnut shell as a worthless agricultural waste by a thermal decomposition method followed by open air calcination. These NPs further were characterized using powder X-ray diffraction, transmission electron microscopy (TEM), scanning electron microscopy, energy dispersive X-ray spectroscope and Fourier transform infrared spectroscopy. Moreover, particle sizes can be tuned by changing cerium source/biomass ratio. To test the catalytic activity of cerium NPs as a heterogeneous catalyst, we selected three-component synthesis of 3,4-dihydroquinoxalin-2-amine. Also, the efficiency of CeO2 NPs as a support for palladium NPs and subsequent use in aerobic oxidation of alcohols has been investigated. TEM image of a recovered catalyst indicates the formation of 12 nm sized palladium NPs within the cerium oxide NPs. The catalyst is quite effective for the oxidation of primary and secondary benzylic alcohols into their corresponding aldehydes and ketones under atmospheric pressure of air. Oxidation of secondary aliphatic alcohols is performed in oxygen atmosphere.

Catalytic Application

Novel ligands have been synthesized by the reaction of readily available aziridines with appropriate nitrogen based nucleophiles under mild conditions. Complexes of different stoichiometry can be readily obtained upon reaction between these ligands and the corresponding copper salts. The enantiomerically pure form of one of the ligands was obtained and applied in the styrene cyclopropanation reaction, where the copper catalyst revealed unexpectedly high diastereoselectivity in comparison with the known systems.Key words: ligands, aziridines, cyclopropanation, copper catalysts, metal complexes.
