The complex Ru(OAc)2(CO)(PPh3)2 (200.5 mg, 0.26 mmol, 1 equiv) suspended in 5 mL of toluene, was reacted with the ligand dppf (167.3 mg, 0.26 mmol, 1 equiv). After stirring at 1 10 ¡ãC for 2 h, the solution was concentrated to about 1 mL and the complex was precipitated by addition of 10 mL n-heptane, filtered, washed 3 times with 4 mL of n-heptane, 3 times with 3 mL of ethyl ether and dried under reduced pressure. Yield: 139.6 mg (67percent) determined to be a mixture of 3 isomers in a ratio of 7/2/1 at -70 ¡ãC, the mixture is interchanging at room temperature. Anal.
