In a 100ml two-necked flask, a suspension of 14 (910 mg, 1.91 mmol) in 30ml of EtOH is brought to reflux and MeOH is added until complete dissolution is obtained (35ml). A solution of LiOTf (2.986g, 19.1mmol) in 3ml of MeOH is added to the mixture, which is then kept at reflux for 30 min. The volume of the mixture is reduced to 20 ml by evaporating the solvent at low pressure, and the white precipitate thus obtained is filtered by washing with EtOH (856mg, 1.57mmol, yield 82%, p.f.: 206-207C)., 33454-82-9

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.33454-82-9,Lithium trifluoromethanesulfonate,as a common compound, the synthetic route is as follows.

In an Ar filled flask, 0.150 g (0.24 mmol) of [RuCI(p- cymene)(R,R-TsDPEN)] and 0.037 g (0.24 mmol) of LiOTf were combined. CH2CI2 (10 ml_) was added and the resulting orange mixture was left to stir at ambient temperature. 0.046 g of AgBF4 was then added. The orange suspension gradually darkened to brown and eventually to deep purple in colour. After 21 hours, the suspension was filtered through a 0.45 mm PTFE syringe filter. The brown filtrate was concentrated to dryness leaving a brown residue. Yield: 0.120 g (68 %). 1H and 19F(1HJ NMR (ppm, CD2CI2) showed that the product was obtained (ratio of the products: 1 :1).
