Novel organic peroxygen reagents for use in organic synthesis,ociated with reagents that have been used in the past but which are now no longer in favour. I will also comment on other work using the reagents that my coworkers and I have developed and also, where appropriate, draw comparisons with other peroxygen reagents, especially .-chloroperoxy-benzoic acid

Homogeneous and heterogeneous catalytic oxidations with peroxide reagents,e, permanganate, with cleaner catalytic technologies in industrial organic synthesis. Catalytic oxygen transfer employing peroxide reagents as the oxygen donor provides an attractive alternative. Virtually all of the transition metals and several main group elements can be used in combination with p

Enantioselective epoxidation with peroxidic oxygen,uch optically active epoxides is the enantioselective epoxidation of olefins by reagents containing peroxidic oxygen. Besides the application of optically active oxidizing agents, hydrogen peroxide in the presence of optical auxiliaries, and molybdenum peroxo complexes with chiral ligands, the Sharp

Synthesis of dicarboxylic acids by transition-metal catalyzed oxidative cleavage of terminal-unsatuustrially produced 10-undecenoic methylester were used as starting materials for the preparation of dicarboxylic esters. Two different reaction routes were applied. Ketonisation of the terminal unsaturated fatty acid esters by Wacker-oxidation using PdCl./CuCl or RhCl./FeCl. as catalysts led to meth

Peracids and free radicals: A theoretical and experimental approach,e stereoelectronic control of the reaction were investigated in detail. Inter- and the intramolecular hydrogen shifts by alkyl radicals were also studied. These results were used in order to undertake selective hydroxylation of hydrocarbons. Finally we turned our attention to the reactivity of elect

Harry Heaneyen geblitzt! Mit welcher Genugtuung hat er damals auch ein improvisiertes Turnfestlein geleitet, das die Morgenh?lzler in Niederurnen zur Einweihung des Hauses zum besten gaben! All den Scharen, die er nicht selber begleiten konnte, weil im Hause so vieles zu ordnen und zu tun war, gab er wenigstens

The study is based on participatory research into a number of cases where implementation needs to meet new data requirements made by policy makers. It is not about ?ndings on - dropower i
