The reaction mixture was filtered through a 2 cm silicon gel pad and subsequently purified on a silica column with hexanes-THF (10:2 v/v) to yield 180 mg of a black crystalline solid (85% based on Ru, Data for 1c are as follows.

    • Synthesis of trans-(PhC≡C)2[Ru2(D(3,5- Cl2Ph)F)3(DMBA-Ph, 2a, trans-(PhC≡C) 2[Ru2(D(3,5-Cl2Ph)F)3(DMBA-I, 100 mg, 0.06 mmol) was stirred with BrZnC6H5 (0.5 mmol) and Pd(DPEphos)Cl2 (5 mg, 0.007 mmol) in 5 mL of THF for 2 h at room temperature. The reaction mixture was filtered through a 2 cm silicon gel pad, and the filtrate was purified on a silica column with hexanes-THF (20:1 v/v) to yield 2a as a black crystalline solid (50 mg, 45% based on Ru, Data for 2a are as follows.
