Aspectos cinéticos, estructurales y de reactividad de los dianiones de bifenilo y tetrafenileno

Abstract

En la presente memoria se aborda el estudio de la reactividad de dianiones de hidrocarburos aromáticos policíclicos (HAPs). En el capítulo I se llevó a cabo una síntesis eficaz del fluorometilciclopropano y posterior estudio como sonda de radicales. Se estudió el mecanismo de reacción a través del cual tiene lugar la alquilación de dianiones de HAP (bifenilo y naftaleno) con fluoruros de alquilo primarios, con el fin de elucidar si este mecanismo transcurre vía TE, o si existe competencia con la sustitución nucleófila bimolecular SN2. En el capítulo II se ha conseguido establecer una ruta eficaz para la síntesis asimétrica del 2,7,10,15-tetra-terc-butiltetrafenileno, obteniendo ambos enantiómeros con excelentes excesos enantioméricos. Se ha llevado a cabo un estudio cinético para el cálculo de la energía de racemización del 2,7,10,15-tetra-terc-butiltetrafenileno.
