Nouvelles réactions de couplage décarboxylatif catalysées par des sels de cuivre et de palladium - Nouvelles réactions de couplage aryl-aryle catalysées par des sels de nickel et de manganèse by Maël Poizat( )

4 editions published in 2013 in French and held by 7 WorldCat member libraries worldwide

The copper-catalyzed decarboxylation of aromatic carboxylic acids has been advantageously achieved by using aliphatic amines like N,N,N',N'-tetramethylethylenediamine (TMEDA) or hexamethylenetetramine (HMTA) as ligands instead of the aromatic heterocyclic amines (quinoline, phenanthroline) used until now. The improvement is significant since the reaction can be performed at a lower temperature (ca. 50 °C less) and the reaction time is clearly shorter. This new catalytic system was developed owing to a careful analysis of the reaction mechanism. The reaction conditions described herein also allow us to perform copper/palladium-catalyzed decarboxylative cross-coupling reactions between 120 to 140 °C instead of 170 °C. Thereby, biaryls and triarylethylenes compounds were obtained in good yields. Moreover, the multi-step synthesis of the anticancer agent (Z)-Tamoxifen was completed using a decarboxylative cross-coupling reaction as the key step. The results reported above could open the way to the development of low temperature procedures. It is worthy of note that, for large-scale applications, it is very advantageous to replace 1,10- phenanthroline by TMEDA which is clearly less expensive. A new reaction of demethylation-decarboxylation of o-methoxy aromatic carboxylic acids was also described. Finally, a cheap and user-friendly nickel/manganese catalytic system was developed for the efficient cross-coupling of functionalized aromatic chlorides with aromatic grignard reagents

Activation de composés aromatiques et hétéroaromatiques pour la formation de liaisons C-C et C-N par catalyse au cobalt by Jeanne-Marie Begouin( )

Transition metal-catalyzed cross-coupling reactions allowing the formation of C-C or C-Heteroatom bonds underlie the synthesis of key intermediates for pharmaceutical, supramolecular chemistry and material sciences. Thereby, the development of these methodologies is prominent and an increasing number of studies are devoted to these processes. However, some metallic catalysts are known to be rather expensive or toxic. Consequently, the development of alternative sustainable catalysts such as cobalt or ironbased catalysts has been studied over the past few years. Cobalt-catalysts have been little-used although they have shown to be effective for various C-C bond forming reactions. Functionalized arylzinc reagents can be readily obtained from the corresponding arylhalides using a CoBr2-catalyzed reaction. First we envisioned using these arylzinc reagents in CoBr2-catalyzed cross-coupling reactions with chlorodiazines and chlorotriazines leading to aryldiazines and aryltriazines. Benzylzinc reagents had also been used in these reactions and we synthesized various benzyltriazines in this manner. We also studied whether we can use other kind of substrates in these reactions. Thus, we performed CoBr2-catalyzed cross-coupling reactions between arylzinc reagents and methylthiopyrimidines or methylthiobenzo[b]thiazole derivatives leading to 2,4-diarylpyrimidines and 2- arylbenzo[b]thiazole. Then, we studied the reactivity of benzonitrile derivatives in direct cross-coupling reactions with arylhalide based on C-CN bond activation using CoBr2 as catalyst. Finally, we also carried out the study of CoBr2-catalyzed C-N cross-coupling reactions for the synthesis of diarylamines

Synthèse de liaisons carbone-carbone via l'utilisation d'une catalyse par des complexes du cobalt by Muriel Amatore( Book )

2 editions published in 2006 in French and held by 2 WorldCat member libraries worldwide

This work is devoted to the realization of direct chemical cross-coupling reactions, using cobalt (II) salts associated to 2,2'-bipyridine or triphenylphosphine. These reactions involve aromatic or heteroamromatic halides or pseudo-halides, as well as a broad range of reagents such as vinylic acetates, activated olefins or alkyl halides. All these cross-coupling reactions are based on the formation, in catalytic amounts, of organometallic derivatives, the aryl-cobalt species. These catalytic intermediates allow us to direct the reactions either mainly towards carbon-carbon bond formation or towards the synthesis of arylzinc reagents, that we obtained in good yields strating from the corresponding aromatic chlorides. This manuscript, divided into four chapters, presents the results we obtained during this research work. The use of various catalytic systems such as COBR2(BPY) or COBR2(PPH3) in association with manganese as reductant, or else COBR2(BPY) or COBR2 in association with zinc powder, allowed us to develop vinylation reactions (chapter I), conjugate addition reactions (chapter II), alkylation reactions via an organozinc reagent or not (chapter III) and lastly, non symetric biaryls synthesis (chapter IV)
Les alcynylphosphines et leurs dérivés : nouvelles voie de synthèse par couplage C-P oxydant application en "click-chemistry by Romain Veillard( Book )

2 editions published in 2014 in French and held by 2 WorldCat member libraries worldwide

This thesis was devoted to the synthesis and the structural modification of alkynylphosphine derivatives. A new method was developed based on an oxidative cross-coupling reaction between various copper acetylides and secondary phosphine oxides (dialkyl, diaryl, alkylaryl, allylalkyl and allylaryl) or secondary phosphine boranes (dialkyl) as organophosphorus coupling partner. In both cases the corresponding alkynylphosphine derivatives were obtained with moderate to good yields. This strategy was applied to the synthesis of a P-stereogenic enantioenriched alkynylphosphine borane. Silyl alkynylphosphine boranes were next engaged in a tandem desilylation/ [3+2] cycloaddition reaction with a set of azides to obtain triazolylphosphine boranes with good to excellent yields. After borane decomplexation the electronics properties of the corresponding triazolylphosphines were evaluated through the synthesis and IR spectroscopic analysis of their rhodium carbonyl complexes. Finally, palladium and copper complexes involving triazolylphosphine ligands were prepared and their catalytic activities were tested

Étude de la réactivité de sels simples du cobalt(I) envers les halogénures aromatiques en absence et présence de cations métalliques (Zn2+, Fe2+, Mn2+) : mécanismes des synthèses électrochimique et chimique de composés arylzinciques by Sylvaine Seka( Book )

2 editions published in 2004 in French and held by 2 WorldCat member libraries worldwide

This manuscript is devoted to a study of the reactivity of simple cobalt(I) salts towards aryl halides, ArX in various conditions: solvent, co-solvent, presence or flot of a metal salt. It is especially shown that the reduction of CoBr2 or Co(BF4)2 leads to a cobalt(I) species which undergoes an oxidative addition in the presence of ArX. The resulting arylcobalt(III) complex is then reduced at the same potential as the starting cobalt(II) compound into an arylcobalt(II) compound. In the presence of zinc(II) salts, the latter undergoes a transmetallation reaction leading to stable arylzinc compounds. These results allowed us to elucidate the mechanisms involved in the electrochemical and the chemical syntheses of arylzinc compounds. Reactivities of cobalt(I) species and arylcobalt(II) compounds have also been studied in the presence of metal salts such as iron(II) and manganese(II). As observed in the presence of zinc(II) salts, these metal salts stabilize the cobalt(I) species affecting thus its reactivity towards aryl halides
Activation d'halogénures ou de pseudo-halogénures aromatiques et formation de liaisons carbone-carbone par catalyse au cobalt : synthèse et réactivité d'organozinciques aromatiques, synthèse de biaryles dissymétriques by Igor Kazmierski( Book )

2 editions published in 2004 in French and held by 2 WorldCat member libraries worldwide

Two features of the catalysis by cobalt(I) complexes, in situ chemically generated from cobalt(II), are discussed in the present work. Firstly, a study of the synthesis of functionalized aromatic organozinc reagents has been undertaken in order to comprehend processes that were developped in the laboratory. This allowed the efficient synthesis of organozinc reagents under mild and optimized conditions, starting from aromatic bromides, as well as from the poorly reactive chlorides and phenol derivatives. Secondly, these organometallics were used in previously unreported cobalt-catalyzed carbon-carbon bond forming reactions, to obtain compounds such as functionalized phenones. The methodology could be extended to reactions that did not require the preparation of organozinc compounds, especially in the case of the synthesis of unsymmetrical biaryls

Développement de nouvelles transformations catalysées au cobalt by Bohdan Biletskyi( )

1 edition published in 2018 in French and held by 1 WorldCat member library worldwide

L'utilisation du cobalt en synthèse et catalyse organiques est reconnue depuis les années 1970, notamment dans la réaction de Pauson-Khand. Dès lors, de nombreux systèmes catalytiques au cobalt ont prouvé leur efficacité dans diverses transformations chimiques telles que les cycloadditions [2+2+2] ou l'activation des liaisons C(sp2)-H. Dans ce manuscrit, sont présentés des transformations chimiques basées sur l'utilisation de catalyseurs au cobalt s'effectuant essentiellement avec économie d'atomes, et les essais de développement des versions énantioselectives.Tout d'abord, l'activité de catalyseurs au cobalt(I) a été établie dans la réaction de cycloisomérisation de diènynes pour obtention de bicycles[4.3.0]. Les études concernant différents paramètres du système catalytique ainsi que le champ d'application sont présentés. Les catalyseurs à base d'acétate de cobalt(II) se sont révélés très efficaces pour les réactions d'hydroalcynylation. L'hydroalcynylation de vinylaziridines a été développée après optimisation du système catalytique et, le domaine d'application selon la nature des réactants a été défini. Finalement, les études préliminaires de l'allylation énantiosélective avec les catalyseurs de cobalt(II) ont été réalisées. Ceux-ci se sont révélés plutôt comme activateurs du groupement carbonyle, compromettant la version asymétrique de la réaction
