Abstract

The invention relates to a process for preparing monofunctional, bifunctional and polyfunctional aromatic olefins of the formula (I) ##STR1## by reacting haloaromatics of the formula (II) ##STR2## with olefins of the formula (III) ##STR3## wherein a palladium compound of the formula (IV) ##STR4## is used as catalyst.
