Resumen
When the [Ru(p-cymene)(μ-Cl)Cl]2 complex is made to react, in dichloromethane, with the following ligands: 2-aminobenzonitrile (2abn), 4-aminobenzonitrile (4abn), 2-aminopyridine (2ampy) and 4-aminopyridine (4ampy), after addition of hexane, the following compounds are obtained: [Ru(p-cymene)Cl2(2abn)] (I), [Ru(p-cymene)Cl2(4abn)] (II), [Ru(p-cymene)Cl2(2ampy] (III) and [Ru(p-cymene)Cl2(μ-(4ampy)] (IV). All the compounds are characterized by elemental analysis of carbon, hydrogen and nitrogen, proton nuclear magnetic resonance, COSY 1H-1H, high-resolution mass spectrometry (ESI), thermogravimetry and single-crystal X-ray diffraction (the crystal structure of III is reported and compared with the closely related literature of II). The cytotoxicity effects of complexes were described for cervical cancer HeLa cells via 3-(4.5-dimethylthiazol-2-yl)-2.5-diphenyltetrazolium bromide (MTT) assay. The results demonstrate a low in vitro anticancer potential of the complexes.

It crystallizes in the monoclinic space group P 2/c with a = 8.6819(5)Å, b = 5.3696(6)Å, c = 19.7645(8)Å, β = 95.138(12)° and Ζ = 2. The crystal structure has been determined by single crystal X-ray diffraction with applied gaussian absorption correction and refined to an Rw-value of 0.027.The Hg22+-ion is coordinated to both amino nitrogen atoms. Strong hydrogen bonds and bridging nitrate ions lead to chain structure.

Resumen
Cette thèse s'est orientée autour de deux axes de recherche distincts. En premier lieu, nous avons exploré la synthèse des 4-hydroxy-1-boryl-1-allenylsilanes, en adoptant une approche innovante à partir d'époxydes acétyléniques et du (triéthylsilyl)pinacolborane. Cette méthode a permis une préparation stéréosélective et stéréospécifique d'allénylboranes, suivant un mécanisme SNi anti. De plus, l'utilisation de ces 4-hydroxy-1-boryl-1-allenylsilanes pour la propargylation des aldéhydes a conduit, de manière stéréosélective, aux 2-alcynyldiols-1,3. Un état de transition impliquant une structure à six chaînons fermés a été proposé pour cette transformation, suggérant un mécanisme SE2’. L'ampleur et les limitations de ces deux processus ont été rigoureusement examinées. Ensuite, le second aspect de cette thèse a concerné la synthèse de composés hétérocycliques à partir du 2-aminobenzonitrile, en mettant l'accent sur le 1,2,4-triazole. Nous avons par la suite élaboré des dimères et étudié leur réactivité envers des électrophiles, tels que le hexaméthylphosphoramide, avec l'objectif de créer des dérivés de diazaphorine. À l'heure actuelle, une analyse est en cours pour évaluer les propriétés antioxydantes des molécules récemment synthétisées, en particulier des dimères iminiques et phosphoazotés
This thesis revolved around two distinct research avenues. Firstly, we delved into the synthesis of 4-hydroxy-1-boryl-1-allenylsilanes, adopting an innovative approach using acetylenic epoxide and silylborane. This method enabled a stereoselective and stereospecific preparation of allenylboranes, following an SNi anti mechanism. Moreover, we employed these allenes for the propargylation of aldehydes, which led to the stereoselective formation of the corresponding 2-alkynyl-1,3-diols. A transition state involving a closed six-membered ring structure was proposed for this transformation, suggesting an SE2' mechanism. The scope and limitations of these processes were meticulously assessed. Subsequently, the second focus of the thesis pertained to the synthesis of heterocyclic compounds starting from 2-aminobenzonitrile, with a particular emphasis on the 1,2,4-triazole. Following this, we synthesized dimers and investigated their reactivity towards electrophiles, such as hexamethylphosphoramide, aiming to generate diazaphorine derivatives. As of now, an evaluation is underway to gauge the antioxidant properties of the newly synthesized molecules, especially the iminic and phosphoazo dimers

Resumen
The electro-optical activity of organic, nonlinear optical (NLO) systems in part depends on the extent of molecular orientation of the NLO moiety. In this investigation, the technique of using infrared absorption spectroscopy to characterize molecular orientation is introduced as a means of characterizing orientational order in poled polymer glasses. A quantitative understanding of this orientation can be used in modeling the field-induced orientation of a dipole as well as for determining the polarizabilities of new NLO substituents. In this initial investigation the orientation of organic guest molecules in corona-poled guest/host systems is investigated with FTIR spectroscopy. The guest molecules include 2-methyl-4-nitroanaline and 4-aminobenzonitrile. For compatibility, we usually used polymethylmethacrylate (PMMA) as the matrix polymer, and it is interesting that some of the PMMA substituent groups also exhibit field-induced orientation. Molecular orientation parameters and relaxation behavior of these systems will be presented.
