In situ Raman spectroscopy is rapidly becoming a very popular catalyst characterization method because Raman cells are being designed that can combine in situ molecular characterization studies with simultaneous fundamental quantitative kinetic studies. The dynamic nature of catalyst surfaces requires that both sets of information be obtained for a complete fundamental understanding of catalyti...

Trifluoromethylated organic compounds, especially chiral quaternary alcohols bearing trifluoromethyl group are of important intermediates in drugs, agrochemicals and etc.An efficient epoxidation of β-CF3-β,β-disubstituted unsaturated ketones (6) has been developed with environmental benign hydrogen peroxide as the oxidant and F5-substituted chiral qua...

For the enantioselective diversification of a single starting material, different chiral catalyst is usually required for each transformation. Herein, we extend concept catalytically formed auxiliary from hydrogenation to asymmetric cyclopropanation and epoxidation tetra-substituted olefins, alleviating need catalysts in alkene functionalization step. The constructed propargylic amines Pd-catal...

Chemical looping epoxidation (CLE) of ethylene to oxide (EO) presents an exciting alternative the incumbent technology direct with O2(g). In CLE, reaction is still catalysed by Ag but oxygen provided as Olattice from a solid metal oxide, eliminating need and limitations using Here, influence catalyst preparation in CLE investigated. The was impregnated on SrFeO3, which used donor CLE. Temperatu...
