    摘要: The invention relates to process for preparing monofunctional, bifunctional or/and polyfunctional olefins of the formulae (Ia), (Ib), (Ic) or/and (Id), where R1 to R3 are, independently of one another, hydrogen, (C1-C8)-alkyl, CN, COOH, COO-alkyl-(C1-C8), CO-alkyl-(C1-C8), aryl-(C6-C10), COO-aryl-(C6-C10), CO-aryl-(C6-C10), O-alkyl-(C1-C8), O—CO-alkyl-(C1-C8) or N-alkyl2-(C1-C8) and aryl is an aromatic radical containing up to 14 carbon atoms, where aryl is as defined above, and Ar is a heteroaromatic, by reacting haloaromatics, haloolefins or/and heterohaloaromatics of the formulae (IIa), (IIb), (IIc) or/and (IId) with olefins of the formula (III), wherein a mixture of a palladium(0) complex or a palladium(II) salt with phosphite ligands of the formulae (IVa) or/and (IVb) is used as catalyst.
