Pełny tekst źródłaIn the current world, carbon dioxide (CO2) is the major waste of the massive utilization of fossil resources but only few applications have been developed using this compound. In order to take advantage of its abundancy, the development of novel chemical transformation of CO2 to produce fine chemicals is of high interest in the scientific community. In particular, the formation of C-N bond(s) from CO2 and amine compounds unlocks a new way to access high energy and value-added. A second type of highly desirable transformation is the formation of C-C bonds with CO2 so as to synthesize carboxylic acid derivatives. The utilization of hydrosilanes as mild reductants allows the reactions to proceed under 1 bar of CO2 with abundant and cheap metal-based catalysts (iron, zinc) or with organocatalysts. The synthesis of formamides, methylamines and aminals from CO2 are described herein. Ultimately, the catalytic carboxylation of carbosilanes has been achieved for the first time using copper-based complexes. In the specific case of 2-pyridylsilanes, the use of pentavalent fluoride salts allowed us to perform the reaction without catalyst

Pełny tekst źródłaA wide range of nucleophiles could be alkylated through borrowing hydrogen methodology using alcohols as low toxicity alkylating agents. Advantageously, the only byproduct of these high atom economy reactions is water. In this context, nickel supported on silica-alumina (65 wt% Ni/SiO2-Al2O3) was used to create C-C bonds, particularly to perform the α-alkylation of ketones with alcohols, of which methanol. The full characterization of this catalyst was made, before and after use. Ni/SiO2-Al2O3 was found to be recyclable over 5 runs for the α-alkylation of acetophenone with benzyl alcohol. The cross-benzylation-methylation of acetophenone with methanol and benzyl alcohols was also studied. The α-benzylation of phenylacetonitrile by benzyl alcohol was performed with Ni/SiO2-Al2O3. This catalyst was also able to catalyse the N-alkylation of amides with alcohols. In this case, an important leaching of the catalyst in solution was observed. Finally, Ni/SiO2-Al2O3 was also efficient to catalyze an acceptorless dehydrogenative coupling, allowing the synthesis of an indole from aniline and a vicinal diol

Pełny tekst źródłaThis thesis is part of a very general search seek to develop methodologies for environmentally sustainable conversion of small molecules into more valuable substances catalyzed by copper and iron complexes or under metal-free conditions. The work focuses on the functionalization of aromatic rings by C-C or C-N bond formation.In a first chapter, a novel coupling involving an aryldiazonium salt and a nitrogenous nucleophile (CAr-N bond formation) is first described. The method proceeds under mild conditions using a cheap and non-toxic copper catalyst system. The obtained coupling products (Ar-NHet) are of central interest in the pharmaceutical and agrochemical industry. Then in a second part, a method allowing the coupling between aryldiazonium salts and styrene derivatives, using a BuOK / DMF system is presented. This reaction, carried out for the first time in the absence of catalysts based on transition metals, makes it possible to access to various stilbene units which find numerous applications in pharmaceutical chemistry.A second chapter concerns the use of hypervalent iodine derivatives allowing the functionalization of aromatic or vinyl substrates. A first method describes a direct triflimidation reaction of acetanilide compounds with an exclusive selectivity in the para position. Two reactions conditions have been established for this functionalization. One uses a stoichiometric amount of PhI(OAc)2 and another uses a catalytic amount of iodotoluene (in-situ generation of iodine (III)). This transformation resulted in the formation of CAr-N bonds in the presence of lithium bis (trifluoromethane) sulfonimide (LINTf2) as the nitrogen nucleophile. In a second part, we have shown that bisphosphoranilidene iodide (PNPI) can catalyze a selective vinylic trifluoromethylation of styrene derivatives in the presence of a hypervalent iodine reagent (iodine (III)), Togni’s reagent II. Work is under way to try to understand the positive influence of PNPI.A third chapter describes preliminary results of an iron-catalyzed heterocoupling of 4-iodotoluene an phenylithium system allowing the obtention of an honorable yield (54%) during the coupling of 4-iodotoluene with phenyllithium. Another series of tests describes the coupling between aryl halides and primary alkyllithiums. The method seems to be very effective, since very recent work in the literature for similar couplings involving the same reaction partners involves catalysts of iron or palladium

Pełny tekst źródłaThe direct functionalization of C-H bonds offers an attractive, atom- and step-economical alternative to traditional methods based on functional group transformations. Intermolecular C(sp3)-H amination reactions involving nitrene intermediates usually proceed with moderate yields and regioselectivities. In this context, new bifunctional compounds were developed and applied to copper and silver-catalyzed C-N bond-forming reactions. These systems, however, have been found to be ineffective under the reaction conditions.Our research has also focused on the iodine(III)-mediated nucleophilic functionalization of anilides. The direct triflation and triflimidation of acetanilides were accomplished with the use of affordable and easy-to-handle silver(I) triflate or triflimidate respectively, under mild oxidative conditions, exhibiting perfect regioselectivity for the para position. A complete optimization of the reaction conditions and an evaluation of the scope allowed us to prepare a variety of diversely substituted aryltriflates (and nonaflates) in synthetically useful yields

Pełny tekst źródłaTransition 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

Pełny tekst źródłaThis thesis is one part of a general research of the novel, non-expensive and environmentally friendly methods for the synthesis of the interesting molecules in the pharmaceutical, agrochemical or material field. In particular, the objective consists of creating the C-C and C-heteroatom (S, N, P) bonds by using copper, manganese catalysis or transition-metal-free system.In the first part, a copper-catalyzed palladium-free Sonogashira reaction has been realized under biphasic conditions (water / organic substrates) allowing decreasing the copper loading up to 0.02 – 0.2 mol% and a potential intermediate species of this reaction, corresponding to a copper cluster linked with acetylide moiety, has been identified by X-ray diffraction.In the second part, we described a novel carbon dioxide involved copper-catalyzed system for the methylthiolation of aryl halides using dimethylsufoxide as a source of methylthio group. The presence of carbon dioxide is a crucial factor for the formation of aryl methyl sulfides products and its role is discussed.The third part describes the manganese-catalyzed homocoupling and cross-coupling reactions via the formation in situ of aryllithium from corresponding aryl halides or arenes. According to the experimental conditions, the symmetrical or unsymmetrical biaryls could be obtained. An intermediate complex of manganese which could involve in the reaction mechanism was detected by ESI-MS.Finally, a transition-metal-free system associating DMF with t-BuOK has been developed to realize the arylation of aromatic halide derivatives and various nucleophiles such as pyrazol, imidazole, dialkyl disulfide or diarylphosphine oxide. This project is at a preliminary stage
