Reacciones de activación C-H para preparar 2,5-di(hetero)aril furanos
Resumen
En este estudio se llevó a cabo la síntesis de furanos 2,5-di(hetero)aril sustituidos mediante la doble activación C-H de furano con acetato de paladio, empleando halogenuros de (hetero)arilo y se obtuvieron rendimientos aceptables. La sustitución del furano con grupos arilo que contienen grupos electro atractores proporciona moléculas fluorescentes de bajo peso molecular con posible aplicación optoelectrónica. En cambio, la doble sustitución del furano con anillos de indol que funcionan como grupos electro donadores proporciona compuestos que prácticamente no exhiben fluorescencia.
