Abstract:
This thesis covers the development of catalytic methodologies for the mild and chemoselective hydrosilylation of amides. The first part describes the investigation of the Mo(CO)6-catalyzed reduction of carboxamides. It was found that the reduction could be controlled by tuning the reaction temperature and either amines or aldehydes could be obtained selectively. The system showed an unprecedented chemoselectivity and the amide reduction could take place in the presence of other reducible functional groups such as ketones, aldehydes, and imines. Moreover, the transformation could be performed o

Solar energy is a sustainable resource which has substantial potential to meet the increasing demand for renewable energy. Though there has been some success in harvesting solar energy for electricity production, converting solar energy to chemical energy as fuels is still a challenge due to low efficiency. Since the discovery of TiO2 photocatalysts for splitting water (4) and reducing CO2 (5) to form useful chemical feedstock such as H2, CO and CH4, much research has been done to increase the efficiency of photocatalysts. However, the current conversion efficiency of photocatalysts remains lo

Abstract:
La methode de preparation utilise des carbanions phosphonates lithies (z)::(2)p(y)chrli. Elle realise l'introduction sur le phosphore et le carbone en position 1 de substituants non accessibles par le rearrangement thermique de michaelis-arbuzot. Ce procede est applique a des structures phosphoniques d'interet synthetique et biologique. Ce sont d'une part les alkylidene diphosphonates et d'autre part les formyl-1 phosphonate delta
