As a common heterocyclic compound, it belongs to ruthenium-catalysts compound, name is Dichloro(cycloocta-1,5-diene)ruthenium(II), and cas is 50982-12-2, its synthesis route is as follows.
[HNEt3][7,8-nido-C2B9H12] (0.400 g, 1.71 mmol) was suspended in degassed ether (35 mL). n-BuLi (1.40 mL, 3.50 mmol) was added, giving a pale yellow suspension which was stirred under N2 for 1 h, then heated at reflux for 90 min. The resulting solution was filtered, and the ether removed in vacuo to give a yellow oily solid which was subsequently dissolved in degassed THF (35 mL). [RuCl2(COD)]x (0.560 g, 2.00 mmol) and a large excess of naphthalene were added to the THF solution. The resulting brown mixture was heated at reflux for 90 min, then allowed to cool to room temperature. The brown mixture was filtered through a short silica column eluting with DCM to afford a brown solution, removal of solvent from which yielded a brown solid. This was further purified by column chromatography (1:2 DCM:40-60 petroleum ether) giving a yellow band, followed by preparative TLC (2:1 DCM:40-60 petroleum ether). C12H19B9Ru requires: C 39.85, H 5.30. Found: C 39.87, H 5.53%.
