Des complexes NHC du gallium(III) et de l’indium(III) ont été préparés. Ces composés, simples à synthétiser, se sont révélés être beaucoup plus stables que les sels commerciaux de type MX₃ (M = Ga, In ; X = Cl, Br, I). Ces complexes, une fois activés par AgSbF₆, présentent un fort caractère acide de Lewis. [IPr-GaCl₂][SbF₆] s’est ainsi montré très actif en tant qu’acide de Lewis π et a été utilisé comme catalyseur dans différentes réactions impliquant l’activation de fonctions carbonées insaturées. Il a ainsi permis d’effectuer des hydroarylations inter- et intramoléculaires d’alcynes, d’alcènes et d’allènes. La généralité de cette transformation a pu être démontrée dans une réaction tandem de cycloisomérisation/Friedel-Crafts entre un arényne et un nucléophile aromatique. La capacité des complexes cationiques de gallium et d’indium à activer des alcènes a également pu être mise à profit pour la réduction de dérivés styréniques en présence de cyclohexa-1,4-diène comme source d’hydrogène. Et parce que ces complexes permettent la génération de dérivés du styrène par hydroarylation d’alcynes, une cyclisation réductrice d’arénynes sans précédent a pu être développée. Enfin le complexe [IPr-GaCl₂][SbF₆] a été utilisé dans des réaction impliquant l’eau en tant que réactif. Quelques alcynes ont ainsi pu être hydratés et des esters γ,δ-insaturés ont été transformés en lactones. En résumé, nos complexes cationiques de gallium et d’indium peuvent être utilisés dans des réactions généralement considérées comme relevant du domaine des métaux de transition nobles (Au, Pt, Ru…). / NHC complexes of gallium(III) and indium(III) have been prepared. These compounds, easy to synthesize, proved to be much more stable than the commercially-available salts MX₃ (M = Ga, In ; X = Cl, Br, I). These complexes, once activated by AgSbF₆, show a strong Lewis acid character. For instance, [IPr-GaCl₂][SbF₆] showed a high activity as π-Lewis acid and was used as catalyst in several reactions triggered by the activation of unsaturated C-C bonds such as inter- and intramolecular hydroarylations of alkynes, alkenes and allenes. The versatility of this transformation was demonstrated in a cycloisomerization/Friedel-Crafts tandem reaction between an arenyne and an aromatic nucleophile. The ability of cationic complexes of gallium and indium to activate alkenes was also used for the reduction of styrene derivatives with 1,4-cyclohexadiene as hydrogen source. Also, because these complexes are able to generate styrene derivatives by hydroarylation of alkynes, an unprecedented reductive cyclization of arenynes could be developped. Moreover, [IPr-GaCl₂][SbF₆] was used in reactions involving water as reagent. Several alkynes were hydrated and γ,δ-unsaturated esters were transformed into lactones. In summary, our cationic complexes of gallium and indium can be used in reactions generally catalyzed by noble metals (Au, Pt, Ru…).

This is a hermeneutical study of an attempt to inculturate a Redemptorist parish mission in a black township parish. The purpose of Redemptorist parish mission is conversion and renewal. This study is influenced by - - the spirit of St. Alphonsus Liguori (1696-1787) founder of the Redemptorists - Vatican II (1962-1965) and by - the African Synod (1994); and it uses the systemic stage model of Rambo and the spiral model of Costas, as a framework to understand conversion. The conversion experiences of ten parishioners of St. Peter's parish are used as data for the study. A theological reflection on the ten conversions confirmed the following: that cultural context is important for understanding conversion; that conversion is both a distinct moment and a continuous process; that it is imperative to understand conversion from the perspective of the convert him/herself. For 'mission preaching' to effect genuine conversion it must be inculturated. / Christian Spirituality, Church History and Missiology / Th. M. (Missiology)

The diplomma thesis deals with the Lewis turning point and its impact on the Chinese economy. The work is divided into three main chapters. The first chapter explains the basic concept ,,Lewis turning point" and its position in the global context. Besides W. A. Lewis is also mentioned in a number of other authors dealing with growth theories. Here it is primarily determined whether China has reached the Lewis turning point, which is the impact of this point on the Chinese economy, the labor market and what follows the development of the Chinese economy after reaching this point. The third part is found a connection between Lewis turning point and university/higher education. Part of this chapter are the specifics, trends and especially the problems of the university system in China. The conclusion of this chapter is devoted to a turning point, and its impact on education.

In this thesis I have studied the British author C.S. Lewis´s conversion story as it is presented in his autobiography, more specifically his schooling at Malvern College. I have chosen to study his school period since Lewis himself puts great value on how his youth and school period made him into the person who in the 1930s became a Christian, not only including but putting great emphasis on these events in his conversion story. The purpose of my study is to examine the importance of Lewis’s schooling at Malvern College and the relation it has to his conversion story as written in his autobiography. My focus question is, “Why does Lewis describe his school period in such detail in his conversion story?”. To analyze my material, Lewis’s autobiography, I use a hermeneutic method. To answer the focus question, I use Roy Baumeister´s theory of “self-presentation”, which argues that there are two types of motives regarding why individuals present themselves in a certain way; “pleasing the audience” and “self-construction”. The first motive is that the individuals present themselves in line with thoughts and expectations of a certain group. “Self-construction”, on the other hand, is when individuals present themselves to a general audience and they are motivated, with their presentation, to achieve their own goals. Based on my contextualization of the schooling as a part of the larger conversion story told in Lewis’ autobiography, and especially through my analysis of the part describing his time at Malvern College, as well as through earlier research on the topic, the following are examples of conclusions that I have made: in comparison to prior research, in which each researcher presented one conclusion each, Lewis writes about his schooling at Malvern College for different reasons depending on the context, depending on what Lewis wants to achieve in that part. I have also made a conclusion that even though Lewis takes a firm stand that the events in the book will only be included if they contribute to his conversion story the events, the part I have analyzed in this thesis, does not contribute to the story of how Lewis abandoned atheism and turned to Christianity.

Nature’s biodiversity is complex and filled with beauty and wonder which are all observable on the macroscopic scale. This exquisiteness of nature’s intricacies are mirrored on the molecular level such that substances, large or small, are assembled to serve as signaling molecules, protective agents, and fundamental composites of higher-order frameworks for the operation and survival of life. Over the years, chemists have isolated and synthesized these molecules, known as natural products, to understand and evaluate their functions in biology and potential for medicinal applications. Although bioactive natural products demonstrate medicinal promise, poor pharmacological effects require further derivatization because semisynthesis is not sufficient to refine adverse pharmacokinetics. For some active molecules, isolation results in poor yields. In addition to small quantity isolation, many natural products, reflecting the immense complexity of biology itself, pose difficult synthetic challenges to organic chemists because of skeletal heterogeneity, stereochemical complexity, and substitution divergence. As a result of these synthetic obstacles to natural product utilization, improvements are needed in current chemical approaches, and new innovative methodologies for synthesis and chemical space exploration are necessary. Pharmaceutically relevant frameworks, natural products, and synthetic biologically active molecules are comprised of polycarbocyclic and heterocyclic scaffolds. Traditionally, cycloadditions, transannular transformations, and annulation reactions serve as powerful methods for polycyclic formation. In order to assemble diverse polycycles, donor-acceptor cyclopropanes are useful, versatile synthetic equivalents for C-C bond formations. By taking advantage of the strain within these unique, polarized systems, differing molecular architectures can be accessed directly to perform contemporary organic synthesis. Moreover, the donor-acceptor cyclopropanes initially utilized in these studies provided a fundamental basis for new methods to synthesize other relevant scaffolds. Unique, efficient, Lewis acid-catalyzed intramolecular cyclization strategies for the construction of functionalized polycycles using Friedel-Crafts-type alkylation sequences are presented to expand the reaction repertoire of the molecular architect. Generally, products were formed from commercially-available starting materials in high yields with broad scope. The methodologies were demonstrated to be modular, operationally simple, and amenable to different substitution patterns and functional groups to afford tetrahydroindolizines, heteroaromatic cyclohexenones, hydropyrido[1,2-a]indoles, pyrrolo[1,2-a]indoles, pyrrolo[3,2,1-ij]quinolines, pyrrolizines, and tetrahydrobenzo[ij]quinolizines. To demonstrate the utility of the methodologies devised, progress toward, (±)-rhazinicine, a natural product, is discussed. This dissertation is organized into six chapters: (1) an introduction, paradoxical stress and molecular strain’s utility in synthesis; (2) annulation reactions for the formation of heteroaromatic cyclohexenones; (3) hydropyrido[1,2-a]indole formation via an In(III)-catalyzed cyclopropane ring-opening/Friedel-Crafts alkylation sequence; (4) tetrahydroindolizine formation and progress toward the total synthesis of (±)-rhazinicine (5) pyrrolo[1,2-a]indole synthesis using a Michael-type Friedel-Crafts cyclization approach; and (6) a versatile protocol for the intramolecular formation of functionalized pyrrolo[3,2,1-ij]quinolines.
