The study and the development of innovative metal-catalysed systems for the oxygenation of organic molecules with sustainable oxidants, and especially molecular oxygen, O2, or hydrogen peroxide, H2O2, is a very attractive perspective for the Chemical Industry. In the Thesis project, different strategies have been addressed to implement benchmark oxidative transformations, including the autooxidation of benzylic derivatives, the hydroxylation of aromatic hydrocarbons and the epoxidation of olefins. In all cases, the research approach has been based on some key issues, namely the integrated us

Abstract:

The oxidation of alcohols and olefins is a pivotal reaction in organic synthesis. However, traditional oxidants are toxic and they often release a considerable amounts of by-products. Here, two IronIII-based systems are shown as oxidative catalyst, working in mild conditions with hydrogen peroxide as primary oxidant. An efficient catalytic system for the selective oxidation of several alcohols to their corresponding aldehydes and ketones was developed and characterized, [Fe(phen)2Cl2]NO3 (phen=1,10-Phenantroline).

Abstract:

Oxidations are an important kind of reactions which are traditionally performed using stoichiometric oxidants that generate a large amount of waste. Syn-dihydroxylation of alkenes is a paradigmatic example because it is a cornerstone reaction in organic synthesis that still relies in the use of heavy metal oxides, specially Os and Ru based oxides in catalytic amounts, but also KMnO4, in stoichiometric amounts. Acetonitrile and halogenated solvents are widely used solvents in these reactions because of their robust nature against oxidants. However, metal catalyzed oxidations in green solv

Abstract:

Au niveau industriel, l'accès aux acides azélaïque et pélargonique, composés à forte valeur ajoutée, est possible grâce à une réaction d'ozonolyse de l'acide oléïque. Cependant, cette méthode présente certains désavantages sur le plan écologique. Le but de cette étude a donc été de développer une méthode alternative à ce procédé industriel, visant à limiter autant que possible les impacts écologiques, directs ou indirects, lors de la synthèse des acides azélaïque et pélargonique. Nous avons ainsi montré qu'un clivage en deux étapes peut être préférable à un clivage oxydant en une étape. Notre

Abstract:

U okviru ove doktorske disertacije ispitani su i utvrđeni optimalni uslovi za proces lju&scaron;tenja semena suncokreta visokooleinskog tipa, kao sirovine za proizvodnju ulja. Sprovedena istraživanja su dala podatke o optimalnim vrednostima sadržaja vlage u semenu i pritiska vazduha u lju&scaron;tilici na osnovu kojih je utvrđen model za lju&scaron;tenje semena. Sprovedenim istraživanjima obuhvaćeno je i ispitivanje uticaja promenljivih tehnolo&scaron;kih parametara, sadržaja ljuske u opsegu od 0 do 20% i sadržaja nečistoća u opsegu od 0 do 10% na sastav i kvalitet hladno presovanih ulja i pog

Abstract:

Dans un contexte de raréfaction des ressources pétrolières et de pressions environnementales, l’industrie chimique a besoin d'innover en développant de nouvelles filières destinées à l'élaboration de bioproduits, à partir de matières premières d'origine végétale. Les acides gras insaturés obtenus à partir des huiles végétales, constituent ainsi une ressource renouvelable à fort potentiel permettant de diversifier les approvisionnements d'origine pétrolière. Notre intérêt s'est porté sur la réaction de scission oxydative d’acides gras insaturés pour conduire à des monoacides et diacides à chaîn
