Résumé :

This thesis studies the interaction between free radical species and supported noble metal nanoparticles (silver and gold) in the context of oxidation reactions. The peroxidation of cumene is the first reaction to be discussed and the difference in peroxidation product distribution using silver nanoparticles (AgNP) versus gold nanoparticles (AuNP) is examined. Specifically, cumyl alcohol is obtained as the major product obtained when using supported AuNP, whereas cumene hydroperoxide is favoured for AgNP. Such variations in product distribution are partially explained by the differences in the

Résumé :

O-acyl-N-benzyllactamides are obtained in good yield by reaction of 4-benzyl-5-methyl-1,3-oxazolidine-2,4-diones with Grignards reagents and with lithium alkyls. Three alkanes and two ethers were oxidised with ozone in dichloromethane solution or in aqueous pH 3 suspension. Cyclodecane and cyclododecane were converted into the corresponding cycloalkanones. n-decane was converted into a mixture of isomeric n-decanones and carboxylic acids. An ester was formed from the ethers. Hence, one of the methylene groups of these substrates is generally converted into a carbonyl group. Some of these react

In order to find the possible active sites for CO oxidation, we investigated the O2 -adsorption behavior on different position of 1 and 2 B-doped carbon nanotubes and find the most stable structures of adsorbed O2 are flat on C-B site of both nanotubes with the adsorption energies of -0.85 and -1.29 eV, respectively. Then we investigated the catalytic reaction paths of CO oxidation,

First, we consider the O2 adsorption and use Bader charge to analysis, the favorable adsorption sites are C-N site and C-C-1 site. The calculation results show that most stable adsorption energy are -0.82 and -1.63eV for NCNTs, and -0.84 and -0.99eV for N-C60. Then we use nudged elastic band (NEB) method to

博士<br>國立成功大學<br>化學系碩博士班<br>96<br>The use of radicals in organic synthesis has increased dramatically within the last decades. Radical carbon-carbon bond-forming reactions have grown in importance to the point where chemists are now routinely considered in strategy planning of complex targets. A typical, widely used radical cyclization involves the reduction of a halide or other functional group to a radical with R3SnH, followed by cyclization and reduction of the resulting radical to a hydrocarbon in the chain propagation steps. While this sequence often gives high yields of products, this app
