Efficient Aerobic Oxidation of Alcohols using a Hydrotalcite-Supported Gold Nanoparticle Catalyst

ADVANCED SYNTHESIS & CATALYSIS (PREVIOUSLY: JOURNAL FUER PRAKTISCHE CHEMIE), Issue 11-12 2009
Takato Mitsudome
Abstract Hydrotalcite-supported gold nanoparticles (Au/HT) were found to be a highly efficient heterogeneous catalyst for the aerobic oxidation of alcohols under mild reaction conditions (40,°C, in air). This catalyst system does not require any additives and is applicable to a wide range of alcohols, including less reactive cyclohexanol derivatives. This Au/HT catalyst could also function in the oxidation of 1-phenylethanol under neat conditions; the turnover number (TON) and turnover frequency (TOF) reached 200,000 and 8,300,h,1, respectively. These values are among the highest values compared to those of other reported catalyst systems at high conversion. Moreover, the Au/HT can be recovered by simple filtration and reused without any loss of its activity and selectivity. [source]

Up the TEMPO: A novel, three-component catalyst system consisting of acetamido-TEMPO, copper bromide, and 4-pyrrolidinopyridine not only gives the highest reported turnover frequencies (up to 200 turnovers per hour) for solvent-free aerobic oxidation of primary alcohols to aldehydes at ambient temperature and pressure, but also displays exceptionally high selectivity toward benzylic and allylic primary alcohols.
