Abstract
Disclosed are: a novel palladium catalyst which does not undergo leakage, can be recycled, does not require the use of any phosphorus-containing ligand, and has a high catalytic activity; and a process for producing a novel bisaryl compound using the palladium catalyst. In the production of a bisaryl compound by reacting an aromatic halide with an aromatic boronic acid in the presence of a palladium catalyst and a base, the palladium catalyst comprises a dendrimer containing a silica particle as a core and a palladium compound dissolved in an ionic liquid and supported on the dendrimer.
