Hoveyda-Grubbs second generation catalyst (150 mg, 0.24 mmol) and potassium 2,4,6-trimethylbenzenethiolate 2c (59 mg, 0.31 mmol) were transferred to a 25 mL Schlenk flask, followed by addition of 5 mL of benzene and 1 mL of 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 dark green. The reaction mixture was filtered, and the volume of the filtrate reduced to about 3 mL. Hexane (15 mL) was then added to the dark-green solution under stirring to precipitate the ruthenium complex 4c as a dark green powder (98.5 mg, 55.3%). Further purification was accomplished by dissolving the product in benzene and precipitating with hexane. Crystals for X-ray crystal structure determination were grown by slow diffusion of pentane to a concentrated solution of 4c in fluorobenzene, see FIG. 13 and Table 5.
