Abstract

La presente invención se refiere a un procedimiento para preparar benzofenonas de la fórmula: (VER FIGURA) en donde R1, R2 y R3 representan hidrógeno o etilo, siendo por lo menos uno etilo, Ar es un grupo fenilo substituido en las posiciones 2, 3 ó 4, por de uno a tres grupos seleccionados de cloro, flúor, metilo,carboxi, COOR5 y trifluorometilo; Z es hidrógeno o COR6 en donde R6 es alquilo C1-C4 o fenilo; con la condición de que, cuando R1 es etilo y R2 y R3 son hidrógeno, Ar no es 2,4- o 3,4- dicloro-fenilo, 2- o 3-clorofenilo o 4-clorofenilo caracterizado porque se hace reaccionar un compuesto ácido de la fórmula A-COOX en donde X es hidrógeno o halógeno y en donde A se selecciona del grupo: (VER FIGURA) en donde R1, R2, R3 y Z significan lo anterior, o el grupo Ar, bajo condiciones de acilación de Friedel-Grafts, en presencia de un ácido de Lewis, con un reactivo seleccionado de ArH Y (VER FIGURA) en la que R1, R2, R3 y Z representan lo anterior.
