Sntesis de compuestos de coordinacin con Ligandos Hbridos Pirazol: Aplicaciones en Reacciones catalticas de acoplamiento,Used
Delivery time: 8-12 business days (International)
En esta tesis se describe la sntesis y caracterizacin de una familia de ligandos orgnicos (Npirazol, Oalcohol y Npirazol, Oter), y su utilizacin en la sntesis de complejos con diferentes metales de transicin, preferentemente Pd(II), pero tambin con otros metales tanto del Grupo 10 como del Grupo 12 de la Tabla Peridica. Tambin se ha ensayado la capacidad cataltica de algunos de los complejos de Pd(II) en la reaccin de Heck, y la capacidad de los ligandos Npirazol, Oter en la sntesis y estabilizacin de nanopartculas.En total se han sintetizado un total de 22 complejos. La caracterizacin de los complejos se ha hecho utilizando diferentes tcnicas: Anlisis elementales, Medidas de conductividad, Espectrometra de masas, Espectroscopa de IR, RMN (unidimensionales, bidimensionales) y por difraccin de rayosX en monocristal siempre que ha sido posible adems de medidas de fluorescencia para algunos complejos.
