The invention relates to a process for preparing monofunctional, bifunctional or polyfunctional aromatic olefins of the formula (I) <IMG> ( I ) where R1a to R5a are, independently of one another, hydrogen, C1-C8-alkyl, alkoxy-(C1-C8), acyloxy-(C1-C8), O-phenyl, phenyl, fluorine, chlorine, bromine, iodine, OH, NO2, OSO2CF3, CN, COOH, CHO, SO3H, SO2R, SOR, NH2, NH-alkyl- (C1-C8), N-alkyl2-(C1-C8), CHal3, NHCO-alkyl-(C1-C4), N-alkyl-(C1-C4)-CO-alkyl-(C1-C4), COO-alkyl-(C1-C8), CONH2, CO-alkyl-(C1-C8), NHCOH, NCOO-alkyl-(C1-C4), CO-phenyl, COO-phenyl, CHCH-CO2-alkyl-(C1-C8), CHCHCO2H, PO-phenyl2, PO-alkyl2-(C1-C4), where one of the radicals R1a to R5a can also be <IMG> R6a is hydrogen, alkyl (C1-C8), phenyl, O-alkyl-(C1-C8), fluorine, R7a and R8a are, independently of one another, hydrogen, CN, CO2H, CO2-alkyl-(C1-C8), CONH2, CONH-alkyl-(C1-C4), CON(alkyl)2-(C1-C4)-fluorine, CO2-phenyl, alkyl, (C1-C8)-phenyl, PO(phenyl), Po(alkyl-(C1-C4))2, CO-phenyl, CO-alkyl-(C1-C4), O-alkyl-(C1-C4), NH-alkyl-(C1-C4), PO3H, SO3H, SO3-alkyl (C1-C4), SO2-alkyl-(C1-C4), O-phenyl, by reaction of haloaromatics of the formula (II) <IMG> ( I I ) with olefins of the formula (III) <IMG> ( I I I ) where R1a to R8a are as defined above, where one of the radicals R1a to R5a can also be X and X is iodine, bromine, chlorine, OSO2CF3, OSO2-phenyl, OSO2CH3, wherein a palladium compound of the formula (IV) <IMG> ( I V ) where R1, R2, R3, R4, R5, R6 are, independently of one another, hydrogen, (C1-C4)-alkyl, (C5-C8)-cycloalkyl, (C1-C4)-alkoxy, fluorine, NH2, NH-alkyl(C1-C4), N(alkyl)2-(C1-C4), CO2alkyl-(C1-C4), OCO-alkyl-(C1-C4) or phenyl, or R1 and R2, R2 and R3, R3 and R4, R5 and R6 together form an aliphatic or aromatic ring, and R7, R3 are (C1-C8)-alkyl, (C3-C12)-cycloalkyl, substituted or unsubstituted aryl and Y is an anion of an inorganic or organic acid, is used as catalyst.
