| 摘要 |
The invention relates to a process for preparing a (hetero)aromatic olefin, in which an optionally substituted olefin is arylated in the presence of a metal (compound) containing a metal from any one of groups 8, 9 or 10 of the Periodic System, a compound being chosen as the arylating agent that has the formula (1): Ar-CO-YCOA where Ar stands for an optionally substituted (hetero)aromatic group; A stands for an optionally substituted (hetero)aromatic or aliphatic group, an optionally substituted alkoxy or aryloxy group or a bond with Ar; Y stands for an optionally substituted heteroatom, and the arylation is carried out in the presence of a halide. As the arylating agent use is preferably made of an aromatic carboxylic anhydride, for example benzoic anhydride. Suitable for use as the (metal) compound containing a metal from any one of groups 8, 9 or 10 of the Periodic System is a compound from the group comprising PdCl2, PdBr2, PdI2, Na2PdCl4, Na2PdCl6, Pd2(dibenzylidene acetone)3, (Ph3P)4Pd, (PhCN)2PdCl2, Pd(OAc)2 and PdSO4. Suitable for use as the halide is a compound from the group comprising halides of alkali metals, quaternary ammonium halides and quaternary phosphonium halides. |
