Patent number: 5550236Abstract: A process for preparing polycyclic aromatic compounds by cross-coupling aromatic boronic acids with aromatic halogen compounds or perfluoroalkylsulfonates in the presence of metallic palladium, if desired applied to a support material, as catalyst, wherein the coupling is carried out in the presence of a ligand and a base. The process of the invention allows the yield of polycyclic aromatic compounds to be significantly increased in comparison with processes not using a ligand and thus allows a yield optimum for the Pd(0)-catalyzed cross-coupling of aromatic boronic acids with aromatic halogen compounds to be achieved.Type: GrantFiled: April 24, 1995Date of Patent: August 27, 1996Assignee: Hoechst AktiengesellschaftInventors: Hubert Schlosser, Rainer Wingen, Javier Manero
