Abstract
Procedimiento para la obtención de acetofenonas, que están substituidas por fluoralquilo sobre el núcleo aromático, a partir de fluoralquilanilinas y acetaldoxima, en el que se prepara una solución de sal de diazonio correspondiente a partir de una fluoralquilanilina y esta se hace reaccionar con acetaldoxima en presencia, al menos, de un compuesto de cobre, caracterizado porque no se añaden sales tamponantes ni agentes reductores, llevándose a cabo la reacción a 20 hasta 50 C en presencia de iones halogenuros y, a continuación, se calienta a una temperatura en el intervalo de 70 hasta 110 C.
