Testo completoBis ylides are divalent carbonated s pecies on which a central carbon atom bears two negative charges, both stabilized by two α, positively charged heteroatoms. Selectively transferring the central carbon atom, using both ylides simultaneously is of great interest for synthetic chemists. Such atomic carbon sources are scarce, as most of the bis ylides developed until now were too tightly bind to his ligands. With this in mind, this thesis ambitions to develop bis ylides and other reactive species containing an iodonium ligand, an extremely labile fragment which could allowed an efficient liberation of the central carbon atom. The first chapter is dedicated to the state of the art of “carbon(0)” compounds and their application as atomic carbon sources, as well as the structure and reactivity of hypervalent iodine compounds. The second chapter is about releasing bis ylides by cleaving a covalent bond, either a P C bond from a phosphine oxide stabilized mixt phospho iodonium ylide, or a Si C bond from a silane stabilized mixt phospho iodonium ylide. A third chapter explains our attempts to obtain bis ylides precursor by direct iodination of nucleophilic phosphonium or sulfoxonium ylides. The last chapter is dedicated to our attempt to develop an iodonium yldiide, in which only one of the two negative charges borne by the central carbon is next to a positively charged heteroatom, the other being stabilized by a sulfonyl mesomeric and inductive effects. The results of those attempts allowed us to describe the reactivity of a new nucleophilic, mono stabilized iodonium ylide towards aldehydes

Testo completoThe main goal of this work is to examine the capabilities of M05-2X, M05-2X+D3, PBE0, PBE0+D3, PBE, PBE+D3 and M11 functionals with and without inclusion of D3 dispersion correction for the accurate description of medium sized organometallic compounds and therefore their use for the determination of study of the equilibrium structure, the stability, the spectroscopy and the chemical bonding (covalent, charge transfer and van der Waals) of Znq+Im (q = 0,1,2) complexes. This is done through close comparisons of the results obtained by the M05-2X, M05-2X+D3, PBE0, PBE0+D3, PBE, PBE+D3, M11 functionals with and without inclusion of D3 dispersion correction and those from the standard ((R)MP2 and (R)CCSD(T)) and explicitly correlated ab initio methods (R)CCSD(T)-F12 and (R)MP2-F12. Therefore, we definitely establish that M05-2X+D3 and PBE0+D3 in connection with the 6-311++G(d,p) basis set are the methods of choice for the accurate description of medium sized organometallic compounds. This is illustrated through a systematic study of Zn+qIm of (q=0, 1, 2) complexes which play crucial roles in chemical, biological and industrial domains. Through these comparisons, we show that the results obtained at the M05-2X, M05-2X+D3, PBE0, PBE0+D3, PBE, PBE+D3, M11 levels are in good agreement with those explicitly correlated (R)MP2-F12 and (R)CCSD(T)-F12 methods. Through these comparisons, our study establishes the ability and reliability of M05-2X(+D3) functional for the accurate description of covalent and noncovalent interactions between Znq+ and Im since it leads to close agreement with the large ab initio techniques. PBE0 and M11 may be used also for that purposes. Then, we used high performance M05-2X and PBE0 functionals with and without inclusion of D3 dispersion correction in connection along with the 6-311++G(d,p) basis set to study the equilibrium structure, the stability, the spectroscopy and the chemical bonding (covalent, charge transfer and van der Waals) of Znq+Imn (q = 0, 1, 2, n = 1−4) complexes. This work, at the microscopic level, is useful for understanding the structural and bonding occurring in naturally zinc-binding sites and to figure out the behavior of much more complex biological systems. This should help for designing new zinc-binding proteins and more generally new metal sites in known proteins or ZIFs. The structural backbone of ZIFs is constructed from tetrahedral units formed by one bivalent metal ion (M2+ = Zn2+/Co2+) and four imidazolate anions. Such compounds present a well-established structural topology with a large structural diversity. They exhibit a high porosity which is potentially used for gas storage and separation techniques.Such quantities at the microscopic level are needed to deduce the macroscopic and thermochemical properties of these compounds with good accuracy after incorporation into dynamical simulations

The goal of this study is to design a series of active metal complexes for catalyzing various organic chemstry. During the last two decades, stable carbenes, especially N-heterocyclic carbene (NHCs), have been widely used as ligands for transition-metal complexes. Among their most appealing features is their strong -donor ability which can be superior to that of very basic phosphine. The monodentate palladium (0) and bidentate palladium (II) N-heterocyclic carbene complexes which bear amide functionalities have been successfully synthesized and were prepared from the amide-imidazolium salt. The series of palladium (0) complexes included two types of unsaturated N-heterocyclic carbene ligand precursors bearing amide moieties. Besides, the palladium (II) complexes contained bis-bidentate trans-configured isomer and chelating bidentate trans/cis isomers with pyridine-type ligand. All complexes are characterized by NMR analysis and their structural properties are determined by single-crystal X-ray crystallography. Through the study, it can be seen that the hereby palladium (0) complexes obtaining N-heterocyclic carbene and amide moieties with high electron donating property have a most salient advantage, which is able to catalyze with high efficiency in Suzuki-Miyaura、Mizoroki-Heck and direct arylation aryl-indolyl C-C coupling reactions. We also demonstrated using pentafluoroiodobenzene that the palladium (0) complex which contained a steric bulky mesityl functionality and a monodentate amide methyl-blocked moiety can proceed through oxidative addition pathway. This pathway leads to many interesting products and it is difficult to understand the mechanism and carry out the isolation. In this thesis, we resolve the problem by a preparative method such that a very interesting complex was successfully obtained and structurally characterized. Finally, the catalytic results show that the active palladim (0) complexes can deliver higher activities in the C-C coupling reactions under Suzuki、Heck and direct arylation reaction conditions.

Two series of potentially bidentate ligands bearing N-heterocycylic carbene and phosphine moieties were synthesized. For the phosphine moieties, two different substituents with different electronic and steric properties (PPh2 and PCy2) were employed. After successfully isolation of the ligand precusors, palladium(0) complexes bearing these ligands, 4a–i, were prepared. The complexes were characterized by 1H and 31P{NMR} spectroscopy, electron-spray mass spectrometry, elemental analysis as well as X-ray crystallography. Interestinly, the structures exhibit two different orientations for the coordinated maleic anhydride. Complex 4i shows a fluxional behavior in solution and the exchange process has been successfully investigated by theoretical computation. The catalytic properties of these new complexes were examined. Among them, 4a proved to be the most active in Mizoroki—Heck coupling reaction. The substrate scope was then investigated in detail. Palladium(0) complex was never employed as catalyst system in direct arylation raction. Herein, we showed that 4a is very promising in such non-traditional coupling reaction. Finally, we applied the technology of direct arylation to prepare a bitopic ligand, dipa, and successfully obtain some interesting cooridination polymers.
