Abstract

"PROCESSO PARA PREPARAR BENZOFENONAS". Um processo para preparar benzofenonas de fórmula I, em que X pode ser cloro, hidroxila, metoxi ou C~ 1~-C~ 6~-alquilcarbonilóxi, e Y pode ser cloro ou bromo, reagindo um cloreto ácido de fórmula II em que X e Y são como definidos acima com 3,4,5-trimetoxitolueno, que compreende efetuar a reação na presença de a) um hidrocarboneto aromático como um diluente e b) de 0,0 1 a 0,2 % molar de um catalisador contendo ferro, com base no cloreto ácido, c) em temperatura entre 60<198>C e o ponto de ebulição do diluente usado.
