Catalyst-specific C-H/olefin as well as C-H/acetylene coupling has been accomplished for aromatics which contain both keto and imino substituents by simply changing the catalyst. By using Ru(H)<SUB>2</SUB>(CO)(PPh<SUB>3</SUB>)<SUB>3</SUB> as the catalyst, the C-H bond at the position ortho to the carbonyl group reacted to add across an olefin. When Ru<SUB>3</SUB>(CO)<SUB>12</SUB> is used as the catalyst, the C-H bond at the position ortho to the imino group reacted with the olefin.
