Resumen:
This thesis focuses on the study of the metal-catalyzed carbonylation of norbornene. The transformation of this substrate in esters and aldehydes offers potential applications for the production of valuable compounds in fine chemistry and perfumery industry. In this work we have performed studies on the palladium-catalyzed methoxycarbonylation of norbornene bearing monodentate and bidentate phosphine ligands achieving an important control of the selectivity towards the formation of the desired product. Mechanistic aspects of this reaction have been developed using nuclear magnetic resonance methods, including High-Pressure techniques. Finally, we have studied the asymmetric rhodium-catalyzed hydroformylation of norbornene using chiral 1,3-diphosphites ligands derived from carbohydrates. These catalytic systems have shown high activities with excellent stereoselectivities and moderate enantioselectivities.
