Downstream synthetic route of 34946-82-2

The synthetic route of 34946-82-2 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.34946-82-2,Copper(II) trifluoromethanesulfonate,as a common compound, the synthetic route is as follows.

Ligand L2/L2? (15.2 mg, 63 mumol) was dissolved in ethylacetate (5 mL) and a solution of Cu(OTf)2 (11.4 mg, 31.5mumol) in ethyl acetate (3 mL) was added. The blue precipitatewas isolated by filtration with suction and dried at air;yield: 26 mg (98%). Crystals suitable for X-ray diffractionanalysis were obtained when a solution of the precipitatein the necessary amount of ethyl acetate was concentratedby slow evaporation.
