    Abstract: The invention relates to polyhalogenated cinnamic acids and cinnamic acid derivatives produced by reacting diazonium salts, which are accessible from polyhalogenated anilines, with acrylic acid or acrylic acid derivatives in the presence of a homogeneous catalyst containing palladium, at temperatures between -5 and +100 DEG C. Part of the cinnamic acids and cinnamic acid derivatives produced in this way is novel. Cinnamic acids and cinnamic acid derivatives produced according to the invention can be used to produce indanones, said indanones constituting precursors for agrochemicals and pharmachemicals and for substances having liquid crystalline properties.
