    • To a two-neck flask were added o-dichlorobenzene (24 mL, oleic acid (0.2 mL, and trioctylphosphine oxide (0.4 g, While the solution was heated at 180°C, a solution of metal carbonyl, Co2Rh 2(CO)12 (1.0 g) in 6 mL of o-dichlorobenzene was injected into the flask. The resulting solution was heated at 180°C for 2 h. After the solution was cooled, the solution was concentrated to a of ca. 10 mL by distillation. To the concentrated solution were added 200 mL of THF and then flame-dried charcoal 2.0 g, The resulting THF solution was refluxed with stirring for 18 h and then cooled to r.t. under nitrogen atmosphere. After the solution was filtered, the precipitate was washed successively with Et 2O, CH2Cl2, acetone, and MeOH and dried in vacuo
