In this doctoral thesis, the mechanism of the Lewis base-mediated aza-Baylis-Hillman reaction was examined. Intermediates of the reaction were intercepted and structurally characterized, an extensive kinetic study was performed and the effects of Brønsted acidic co-catalysts on the reaction mechanism were examined. In addition, other mechanistic aspects like reversibility, stability of the stereocenter and chirality transfer from the catalytic system to the reaction product were studied. This mechanistic study provided useful information for the rational design of an appropriate chiral catalytic system. Several potential catalytic systems were synthesized and tested. The most successful system involved a reaction medium, an ionic liquid, as the source of chirality. With this system, enantioselectivities up to 84% ee were obtained in the triphenylphosphine-catalyzed aza-Baylis-Hillman reaction of aromatic tosylaldimines and methylvinyl ketone.

The model of a fluidized bed reactor for the hydrochlorination reaction of silicon to trichlorosilane was developed. In Detail, the reaction of metallurgical silicon with silicontetrachloride and hydrogen, the reaction with addition of a copper catalyst and the reaction with additional amounts of hydrogenchloride were examined. Therefore, experimental data of the reactions in a fixed bed and a fluidized bed reactor were analyzed by modeling and simulation. An equation considering interacting of adsorbed species on the catalytic metals fitted the kinetics best. During reactions the catalytic metals were deactivated. The influence of hydrodynamic in the fluidized bed reactor was described by a modified model from literature. Furthermore, different changes of particle morphology and different abrasion effects in the fluidized beds were present. With the developed reaction model simulations of a continuously operated technical fluidized bed reactor were performed. The technical reaction was strongly influenced by the way the particle morphology changed.
