Texto completo da fonteAlkoxyamines are molecules well-known for their abilities to generate radicals from C-ON bond homolysis. This homolysis can be induced by various methods like thermally, by photocatalysis or by enzymatic activation. In addition, it is easy to modulate their chemical properties by modifying their structure. Thus we can imagine many various applications for these compounds. Here we will describe the synthesis of new alkoxyamines and investigations about their properties. These alkoxyamines have ben developed in order to acquire new knowledge about their reactivity, but also to improve their structures with respect to innovative applications like theranostic, or some new homolysis pathways like localized plasmon resonance

Texto completo da fonteThe reactivity of ethyl α-bromoacrylate and ethyl benzylidene malonate towards dialkylzincs in aerobic medium was studied in order to evaluate the capacity of tertiary α-alcoxycarbonyl radicals to undergo SH2 at zinc leading to a zinc enolate. The use of ethyl α-bromoacrylate allowed the synthesis of cyclopropanes and keto-esters. With the second substrate, the addition of the alkyl group was shown to be reversible. The inhibitor effect of additives like TMSCl or CuCl suggested that zinc peroxydes formed in situ could play a key role in the process. Theoretical studies highlighted the crucial role of the stabilization of the zinc enolate through the formation of a 5 or 6-membered chelate. Regio- and stereoselective synthesis of tri- and tetra-substituted enamides was achieved through the carbozincation of ynamides in the presence of dialkylzincs and CuI or FeCl2 as catalyst. CuI was shown to be more efficient and less substrate-dependent than FeCl2. Molecular modelings were performed to better understand this phenomen. Finally, intermolecular addition of sulfanyl radicals onto ynamides was revisited. Theoretical calculations and experimental results showed that the regio- and stereo-selectivity of the process depended on the nature of the substituent on the carbon in β position of the nitrogen atom and on experimental conditions. Unprecedented intermolecular addition of a carbon-centered radical has been described and opened new perspectives for the synthesis of original tetrasubstituted enamides
Vallet, Anne-Laure. "Réactivités de NHC-Boranes Soufrés". Thesis, Paris 11, 2014. http://www.theses.fr/2014PA112261.
Texto completo da fonteAlong with the development of green chemistry, it became necessary to avoid toxic metallic complexes in organic reactions and replace them by more sustainable compounds. An hydrogen donors for radical reactions, trialkylstannanes are still widely used. NHC-boranes seem to be good substitutes for deoxygenation reactions. However, dehalogenation reactions are less effective and polar reversal catalysis was used. This work was the starting point of this Ph.D thesis where the synthesis of new NHC-boranes bearing a B-S or B-N bound is developed. The study of the properties of these new complexes was performed and applications in organic chemistry as well as in polymer science were found. Besides, to study polar effects on the formation and on the reactivity of boryl radicals, a new family of carbene-boranes was synthesized
