Recyclable Solid Ruthenium Catalysts for the Direct Arylation of Aromatic CH Bonds

Environmentally benign catalyst: A PPh3-modified Ru/CeO2 catalyst showed excellent catalytic activity toward direct CH arylation by using various aryl chlorides in the reaction (see scheme). The catalyst was found to act heterogeneously and could be recycled without significant loss of activity. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
