Abstract

Procedure for obtaining o-halogen-isopropenylbenzenes of formula **(See formula)** where Hal means chlorine or bromine and X means hydrogen, chlorine or bromine, at least one of the residues X is chlorine or bromine and at least one of the residues Hal and X means bromine, characterized in that cumoles of formula **(See formula)** Where Hal and X have the meanings indicated above, they are α-halogenated, preferably in the presence of a solvent, in the liquid or gas phase, at temperatures between -50 and + 400ºC, preferably between -30 and + 100ºC; and then the halogenated hydrogen dissociates from the side chain, at temperatures between 10 and 80ºC.
