Abstract
Procédé consistant à effectuer une bromation complémentaire dans un solvant organique qui est de préférence le bromure de méthylène et en présence d'un catalyseur de bromation qui est un halogénure d'aluminium choisi entre le bromure d'aluminium. Ce procédé permet la transformation des produits sous-bromés en produits perbromés.
