반응 단계

[RuCl2 (1,3,5-triisopropylbenzene)]2 was prepared by stirring a suspension of [RuCl2 (P-cymene)]2 (3 g) in 120 mL 1,3,5-triisopropylbenzene (Aldrich, 97%) for a total of 8 hours at 190° C. under N2. The solution was cooled to room temperature and then placed in a refrigerator for 2-3 days. Solids were collected by cold filtration, washed with heptane, and dried in a vacuum oven at 70° C. A red-brown solid product was obtained (3.25 grams). 1H NMR analysis of this product was consistent with the material being 90+ % pure [RuCl2 (1,3,5-triisopropylbenzene)]2 with a small amount of unreacted [RuCl2 (p-cymene)]2. 1H NMR data for [RuCl2 (1,3,5-triisopropylbenzene)]2 (CDCl3 solvent): δ 1.3 (d, 18H), 3.1 (m, 3H), 5.2 (s, 3H).
