Abstract:
Since its discovery in 1979, the Suzuki-Miyaura (SM) reaction has become one of the most widely utilised tools for carbon-carbon bond formation. The palladium catalysed coupling of an organoboron and organohalide compounds proceeds through a three-stage mechanism of oxidative addition, transmetalation and reductive elimination. The transmetalation of boronic acids to a palladium(II) complex has been widely studied. However, very little is known about the transmetalation of boronic esters, which are commonly used as an alternative to unstable boronic acids. Whether these species undergo direct

Abstract:
Boronic acids and esters are one of the most widely used compound classes inorganic chemistry. Recently, diboron systems have emerged as a powerful approach towards complex molecule synthesis. Selectivity in these systems is typically achieved through the use of protecting group strategies in which one boron residue is rendered unreactive under the prevailing reaction conditions, allowing selective manipulation of an unprotected unit. However, while these methods offer excellent selectivity, they do have the drawback of requiring additional synthetic manipulations, i.e., removal of the protect

2-Dodecyl benzotriazole (BTz) and benzothiadiazole (BTd) containing copolymers poly(4-(2-dodecyl-2H-benzo[d][1,2,3]triazol-4-yl)benzo[c][1,2,5]thiadiazole (P1), poly(4-(5-(2-dodecyl-7-(thiophen-2yl)-2H-benzo[d][1,2,3]triazol-4-yl)thiophen-2-yl)benzo[c][1,2,5] thiadiazole (P2) and poly(4-(5-(2-dodecyl-7-(4-hexylthiophen-2-yl)-2H-benzo[d] [1,2,3]triazol-4-yl) -3-hexylthiophen-2-yl) benzo[c][1,2,5] thiadiazole (P3) were synthesized via Suzuki polymerization. Electrochemical and optical properties of the polymers were analyzed. The fabrication of solar cells were carried out and current density-vo

Abstract:
Le but principal de ce travail a été de mettre en évidence le potentiel synthétique de nouvelles bases mixtes fer-lithium dans des réactions de déprotométallation en série aromatique. Dans un premier chapitre, les travaux de la littérature sur les composés fer-métal alcalin et notamment les bases ont d’abord été exposés. Notre étude a permis d’optimiser une nouvelle base fer-lithium et a montré la capacité de celle-ci à réaliser des réactions de déprotonation relativement chimiosélectives et efficaces. Les paramètres de la réaction de déprotométallation ont été optimisés en utilisant l’iode co

Abstract:
Ce mémoire est subdivise en deux parties. La première partie concerne la synthèse de pyrazoles présentant un intérêt sur le plan agrochimique. En effet, le noyau pyrazole est présent dans de nombreux composes ayant des activités biologiques diverses et en particulier antifongique. Au cours de ce travail, nous avons développé diverses approches convergentes de pyrazoles diversement substitués au moyen de réactions de couplages croisés pallado-catalyses sélectifs et séquentiels à partir de pyrazoles possédant différents points d’encrages. Dans la deuxième partie, nous nous sommes intéressés à la
