Повний текст джерелаThe awareness by society of the concept of sustainable development has led chemists to rethink all industrial processes through the twelve principles of green chemistry. In this “green” approach to chemistry, catalysis, in particular with transition metal complexes, occupies a key place: improvement of activities (lower energy consumption), improvement of selectivities (fewer by-products), discovery of new catalytic reactions (less dangerous reagents, clean solvents, economy of atoms, etc.), control of stereochemistry (synthesis of drugs, polymers) ... Unfortunately, the sometimes high cost of catalysts, their difficulties in recovery or recycling is a barrier to their industrial use. The heterogenization of catalysis reactions (catalyst recycling, simplified product purification) and the development of continuous processes are major challenges that meet societal (environment) and industrial expectations. We wish to answer it here by relying on catalysts prepared from chiral phosphine, phosphinocarbene and ferrocenic carbenes (planar and central chirality) ligands synthesized in the team and having demonstrated excellent activities and selectivities in asymmetric catalysis (hydrogenation, Suzuki -Miyaura). These ligands will be functionalized in order to allow their grafting on a solid support. The nature of the supports (spherical silica, mesoporous silica, etc.), the grafting sites (on the surface, in pores or channels) are elements that we wish to study in order to better understand the role of surface interactions and the phenomena of confinement on the activity and enantioselectivity of the supported catalysts

Recently, the N-heterocyclic carbene based Pd catalysts (Pd–NHC) have been widely used in the Suzuki coupling reaction. However, most of the ligands are less reactive in aqueous media. Therefore, organic solvent is required to be used for these reactions. In addition, the biaryl moiety is a central part in the structure of many natural products and drugs, therefore, the synthesis of biaryl structure has been an important topic in organic synthesis. The bis-benzimidaolium salts 78 have been successfully synthesized from commercially available and inexpensive o-phenylenediamine through a series of simple reactions in good yields. These catalysts derived by Pd(OAc)2 and bis-benzimidazolium salts are air and moisture stable, both in the solid state and in solution. Its high efficacy for Suzuki cross-coupling reaction of aryl bromides are found in aqueous media in the presence of Pd-catalyst and reduce the consumption of organic solvent. Functionalized aryl bromides, such as ketone, aldehyde, ester and nitro, are well-tolerated at 40ºC with excellent yields (86-99%). Di-ortho-substituted biaryls could be accomplished at 60ºC in 89-99% yields. In summary, our ligand is able to reduce costs significantly and simplify reaction operations effectively if it is applied to industrial processes.

Palladium homogeneous catalysis is known as a versatile tool for carbon–carbon bond formation in organic synthesis. The Suzuki–Miyaura coupling reaction of aryl halides with arylboronic acids is one of the most important palladium-catalyzed cross-coupling reactions. We use the 2,6-bis(bromomethyl)pyridine and the imidazole corporated with triptycene to make a CNC pincer, then being a ligand to catalyze the Suzuki coupling reaction with the palladium. We found the ligand 1-di is an active catalytic ligand which can giving the good results to react with aryl halides and heterocyclic halides then catalyzed the Suzuki reaction with phenylboranic acid. Under different conditions, the ideal yield could up to 99%. We also functionalized the imidazole salt that incorporate with triptycene, a chiral functional group. Then we catalyzed cycloisomerization of nitrogen-bridged 1,6-enynes proceeded in the presence of a cationic gold complex coordinated with a chiral triptycene incorporated NHCs ligand (S,S)-1-Au-im to give 52% yield of chiral 3-azabicyclo[4.1.0]heptenes with racemic mixture.
