Abstract
Los fullerenos, descubiertos por H. W. Kroto, R. F. Curl y R. E. Smalley en 1985, han recibido una gran atención por parte de la comunidad científica debido a sus notables propiedades electrónicas y fotofísicas, convirtiéndose en una de las moléculas más intensamente investigadas. Teniendo en cuenta sus propiedades únicas derivadas de una constitución química bien definida, los fullerenos se consideran un material prometedor para diversas aplicaciones. Objetivos Síntesis de Híbridos Quirales Metal-Fullereno Diseño y síntesis de nuevos híbridos quirales de fullereno dotados con diferentes metales, con un completo control sobre los nuevos centros estereogénicos creados, con la quiralidad centrada en el metal. Actividad Catalítica de Híbridos Quirales Metal-Fullereno Se pretende evaluar la eficiencia de estos nuevos híbridos en reacciones fundamentales de transferencia de hidrógeno y su capacidad para ser reutilizados manteniendo la eficiencia. Selectividad en Fullerenos Superiores Se pretende desarrollar nuevas metodologías sintéticas basadas en condiciones suaves para obtener isómeros puros de [70]fullereno con un alto grado de selectividad. Reactividad Química en Fullerenos Endohédricos Síntesis de pirrolidinas enantioméricamente enriquecidas de HF@C60 y estudio del efecto que produce la mólecula de dentro en el proceso de isomerización cis-trans...

Objectives Synthesis of Chiral Metal/Fullerene Hybrids Design and synthesis of new chiral fullerene hybrids endowed with different metals, with a complete control over the new stereogenic centers, specifically with a metal-centered chirality. Catalytic Activity of Chiral Metal/Fullerene Hybrids Evaluate the efficiency of these new hybrid catalysts in fundamental hydrogen transfer reactions and the ability to be reused maintaining efficiency. Selectivity in Higher Fullerenes Development of new synthetic methodologies based on mild conditions for obtaining [70]fullerene derivatives with a high degree of selectivity. Chemical Reactivity on Endohedral Fullerenes Synthesis of enantiomerically enriched HF@C60 pyrrolidines and study of the effect of the incarcerated molecule on the cis-trans isomerization process...
