301224-40-8, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride, cas is 301224-40-8,the ruthenium-catalysts compound, it is a common compound, a new synthetic route is introduced below.
Hoveyda-Grubbs second generation catalyst H2 (104 mg, 0.16 mmol) and potassium 2,6-dimethylbenzenethiolate (34 mg, 0.19 mmol) 2b were transferred to a 25 mL Schlenk flask, followed by addition of 4 mL of toluene and 1 mL THF under argon. Then the mixture was stirred vigorously at 20 C. for 30 min. During this time the color of the mixture turned from light green to a slightly darker green. The reaction mixture was filtered, and the volume of the filtrate reduced to about 3 mL. Hexane (15 mL) was added to the filtrate to precipitate the product 4b as red/orange-brown micro-crystals (86.3 mg, 71%). (0121) Crystals for X-ray diffraction analysis (see FIG. 12 and Table 4) were prepared by dissolving a sample in a minimal amount of toluene, upon which a layer of hexane was added. Red-brown crystals were formed over a period of 3 days at room temperature.
