Abstract:

Complex reaction kinetics of the solid acid alkylation of isobutane with butenes over a proton-exchanged Y-zeolite has been modeled at the elementary step level. Starting with a computer algorithm that generated the reaction network based on the fundamentals of the carbenium ion chemistry, the formation of over 100+ product species has been modeled in order to gain understanding of the underlying phenomena leading to rapid catalyst deactivation and product selectivity shifts observed in experimental runs. An experimental investigation of the solid acid alkylation process was carried out in a f

Abstract:

Formaldehyde is a chemical used widely in the manufacture of building materials. A remarkable example is represented by the Lucite two-step Alpha technology for the large scale production of methyl methacrylate (MMA), the essential building block of all acrylic-based products. Esters and ketones are important intermediates in the manufacture of acrylate esters therefore α-hydroxymethylenation of carbonyl compounds using formaldehyde as a one carbon alkylating agent and subsequent dehydration to the corresponding methylenated derivatives has been explored in the current work. We report a novel

Abstract:

Les microsystèmes sont des réacteurs extraordinaires pour mettre en œuvre des réactions chimiques car ils apportent un rapport de contact entre phases très supérieur à celui en ballon, la possibilité d’hypertrempe thermique tant au chauffage qu’au refroidissement et enfin l’absence d’interaction des réactifs avec les produits. Les dimensions micro-ou nanométriques de ces réacteurs sont très largement compensées par la possibilité de parallélisation à grande échelle de ces réacteurs qui permet une montée en échelle de la production sans nouveau développement.

Abstract:

A series of 3,3-ethylenedioxy-exo- and endo- bornyl esters have been prepared and subjected to α-benzylation using lithium diisopropylamide and benzyl bromide. In the exo-series of esters the diastereofacial selectivity of benzylation was found to improve (up to 34% d.e.) as the steric bulk of the O-alkyl group increased, whereas in the endo-series, a surprising decrease in stereoselectivity was observed as the steric bulk increased – an observation attributed to flexibility of the metal-coordinated endo-enolate system, compared to the relative rigidity of the exo analogues.

Abstract:

The purpose of this doctoral thesis is to investigate and develop catalytic processes mediated by iridium(III) complexes. By understanding the mechanisms, the weaknesses of the designed catalysts can be identified and be overcome in the following generation. The thesis is composed of two general sections dedicated to the synthesis and applications of homogeneous catalysts and to the preparation of heterogeneous catalysts based on metal-organic frameworks (MOFs). After a general introduction (Chapter 1), the first part of the thesis (Chapters 2-4, and Appendix 1) covers the use of several homog

Full text

Abstract:

Memory of chirality (MOC) is an emerging strategy for asymmetric synthesis which relies upon the intermediacy of transiently non-racemic reactive species. In these reactions the configuration of the sole stereogenic center of the enantiopure starting material is "memorized" by a chiral non-racemic conformation in the intermediate; trapping then captures the stereochemical information, and generates a new stereogenic center with high fidelity. We experimentally and computationally studied the highly retentive deprotonation/alkylations of 1,4-benzodiazepin-2-ones (BZDs) that rely upon this strat

Abstract:

With the increasing realization of their involvement in numerous biological processes, synthetic oligosaccharides present promising potential in drug and vaccine discovery. Selective functionalization of hydroxy groups in polyols represent a long-standing goal in chemistry since the chemical synthesis of O-glycosides often requires extensive protecting group manipulation. Organoboron catalysis is a recent strategy for regioselective activation of the equatorial hydroxy group of cis-vicinal diols. Following the initial findings that diarylborinic acid catalyzes the regioselective acylation of c

By varying the reaction condition, the best experimental condition appeared to be the enzyme to alcohol ratio 2 : 1（by weight） and we use HPLC as the tool to separate it and after separation we duly analysed the result so obtained. In a typical procedure, the racemic alcohol and vinyl acetate were taken in the ratio of 10 : 1（by mole） and to this mixture was adde
