With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.50982-12-2,Dichloro(cycloocta-1,5-diene)ruthenium(II),as a common compound, the synthetic route is as follows.,50982-12-2

Complex C-l was also prepared using [RuCl2(COD)]n as a precursor. Thus, a mixture of [RuCl2(COD)]n (309 mg, 1.103 mmol), PPh3 (289 mg, 1.103 mmol) and ligand Id (248 mg, 1.103 mmol) was stirred in toluene (10 ml) at 115C for 24 h in a KONTES pressure tube. After cooling, the resulting brick colored precipitate was filtered on a filter frit, washed with diethyl ether (3 x 10 ml) and vacuum dried to afford 494 mg of a light pink crude material (Found C, 53.43; H, 5.26; N, 4.08%). Recrystallization from hot THF, filtering and layering with diethyl ether, afforded burgundy crystals (261 mg, 32% yield as a THF solvate). Based on NMR analysis, these crystals represent a THF solvate of complex C-l. The crystals were found to lose solvent based on elemental analysis. Elem.
