The catalytic oxidation of toluene over copper oxide supported on natural diatomite was investigated. The catalyst was prepared by the wet impregnation method and characterized by using the Brunauer Emmett Teller (BET), field emission Scanning Electron Microscopy (FESEM), X-ray diffraction (XRD), X-ray fluorescence (XRF) and Temperature-programmed reduction (TPR) analysis. The highest catalytic ...
Pd(OAc)(2) in DMSO is an effective catalyst for the aerobic oxidation of alcohols and numerous other organic substrates. Kinetic studies of the catalytic oxidation of primary and secondary benzylic alcohol substrates provide fundamental insights into the catalytic mechanism. In contrast to the conclusion reached in our earlier study (J. Am. Chem. Soc. 2002, 124, 766-767), we find that Pd(II)-me...
The lack of robust, high-throughput, and sensitive analytical strategies that can conclusively map the structure of glycans has significantly hampered progress in fundamental and applied aspects of glycoscience. Resolution of the anomeric α/β glycan linkage within oligosaccharides remains a particular challenge. Here, we show that "memory" of anomeric configuration is retained following gas-pha...
