Miguel Yus received his BSc (1969), MSc (1971) and PhD (1973) degrees from the University of Zaragoza. After spending two years as a Postdoctoral Fellow at the Max Planck Institut für Kohlenforschung in Mülheim a.d. Ruhr he returned to Spain to the University of Oviedo where he became Associate Professor in 1977, being promoted to Full Professor in 1987 at the same university. In 1988, he moved to the position of Chair in Organic Chemistry at the University of Alicante. He has been Visiting Professor at different institutions and universities including ETH-Zentrum, Oxford, Harvard, Uppsala, Marseille, Tucson, Okayama, Paris, Strasbourg, Bolonia, Sassari, Tokyo and Kyoto. He is co-author of more than 600 papers (and five patents) and has supervised more than 60 Doctoral theses (already presented), and delivered more than 200 lectures, most of them abroad. He has been in the Advisory Board of 20 international journals, among others, Tetrahedron, Tetrahedron Letters, European Journal of Organic Chemistry, Chemistry Letters, The Chemical Record, Current Organic Chemistry, Current Chemical Biology, Jordan Journal of Chemistry, Applied Sciences, and Trends in Organic Chemistry. He is also Editor-in-Chief of Letters in Organic Chemistry and Open Chemistry, as well as Regional Editor of The World Journal of Chemistry. His current research interest is focused on the preparation of very reactive functionalized organometallic compounds and their use in synthetic organic chemistry, arene-catalyzed activation of different metals, preparation of new metal-based catalysts, including metallic nanoparticles, for homogeneous and heterogeneous selective reactions, and asymmetric catalysis. He founded the new chemical company Medalchemy S.L. to commercialize fine chemicals.
Chiral N-sulfinyl imines, especially the corresponding N-tert-butyl substituted derivatives are interesting starting materials in asymmetric synthesis because they are easily accessible (from carbonyl compounds and chiral sulfinamides) in both enantiomerically pure form; the sulfinyl group activates the imine moiety towards nucleophilic substitution so, in the reaction with different nucleophiles an asymmetric induction takes place giving an diastereoenriched product, which can be easily separated into the corresponding pure diastereomers and; the deprotection of the amino group, after the addition of the nucleophile can be easily achieved by simple treatment with hydrochloric acid. In this presentation, the reactivity and synthetic applications of these materials in the ruthenium-catalyzed hydrogen transfer; addition of alkyl zincates and indium-promoted allylation will be considered. Especial attention is paid to the synthetic applications of the mentioned processes, mainly for the preparation of natural or unnatural alkaloids and amino acids.

Fresh Lands Enivornmental Actions, UK
Time : 09:40-10:05
Christopher J Rhodes is the Director of Fresh-lands Environmental Actions. He has catholic scientific interests which cover radiation chemistry, catalysis, zeolites, radioisotopes, free radicals in biology and medicine, electron paramagnetic resonance spectroscopy, and more recently have developed into aspects of environmental decontamination and low-carbon energy production. He has published more than 230 peer-reviewed scientific articles and six books. He is also a published Novelist, Journalist and Poet. His novel “University Shambles” is available in both print and e-book versions, and was nominated for a Brit Writers Award: Published Writer of the Year.
A critical overview is presented of zeolites and their use in practical applications. Specifically considered are their roles as media for selective light-induced oxidations of organic molecules using molecular O2, and the relationship between this phenomenon and the surface electric fields that exist in zeolites. Methods for determining the strength of the zeolite surface fields are discussed using sorbed molecules such as CO with IR detection, and the spin-probes, di-tert-butyl nitroxide and NO, as detected using EPR spectroscopy. The relationship between these surface fields and molecular reorientation energetics for organic free radicals sorbed in zeolites, obtained using muonium as a spin-label, is explored. Finally, results obtained from exposing the naturally occurring zeolite, clinoptilolite to high energy electrons as a means for activating the material toward the selective removal of radioactive caesium and strontium cations from the wastewaters of nuclear power plants are presented.

Here, we show that petroleum can be formed efficiently at normal temperatures and pressures from carbon dioxide and activated water. The CO2- nano-bubble containing water was treated with TiO2 catalysis in the presence of oxygen under UV irradiation. The activated water was mixed vigorously with kerosene or light oil and carbon dioxide to form an emulsion. The emulsion gradually separated into a two-phase solution. After phase separation, the volume of kerosene or light oil, depending on which oil was utilized, increased by 5 to 10%. Oxygen gas is converted to ozone and further to reactive oxygen species such as superoxide anion radicals and hydroxyl radicals. The reactive oxygen species may reduce carbon dioxide to carbon monoxide, as follows, 2 CO2 ⇔ 2CO+O2 (reaction 1), the generated carbon monoxide may form hydrogen from water, as follows, CO+H2O⇔CO2+H2 (reaction 2), as a total, CO2+H2O⇔CO+H2+O2 (reaction 3). All reactions were carried out at room temperature and normal pressure. The oil generation reaction may occur as radical emulsion polymerization in micelles and be written as follows, nCO＋(2n＋1)H2⇒CnH2n＋2＋nH2O (reaction 4). From reactions 3 and 4, mass balance is shown as follows, nCO2＋(n＋1)H2⇒CnH2n＋2＋nO2 (reaction 5).
