With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.246047-72-3,(1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium,as a common compound, the synthetic route is as follows.
Example 5 Synthesis of the Complex 4 According to the Invention [0081] The commercially available complex G (200 mg, 0.24 mmol) was placed in a flask, to which methylene chloride was added (6 ml). This was followed by adding the compound of the formula: (78 mg, 0.47 mmol) and tricyclohexylphosphine (132 mg, 0.47 mmol). The resulting solution was stirred at a temperature of 40 C. for 1 hour. The reaction mixture was introduced at the top of a chromatographic column packed with silica gel (eluent: ethyl acetate/cyclohexane, 0 to 10 vol. %). After evaporating the solvents, the complex 4 was obtained as a brown solid (104 mg, 50% yield).
