54761-04-5, General procedure: A mixture of Ce(OTf)3 (0.1388g, 0.2mmol) and C12H8N2 (phen) (0.005g) was dissolved in a mixture of CH3CN (10ml) and DMF (three drops). After the mixture was stirred for 1h, the ligand L (0.2752g, 0.8mmol) was added to this mixture. Stirring was continued for 4h at ambient temperature. After this time, any insoluble residues were removed by filtration, and the filtrate was evaporated slowly at room temperature for about one month to yield colorless crystalline products.

54761-04-5 Ytterbium(III) trifluoromethanesulfonate 2733225, acatalyst-ligand compound, is more and more widely used in various fields.

54761-04-5, General procedure: These were all prepared in the same way: the example given for Ir?Eu is typical. A mixture of Ir?A (0.043g, 0.04mmol) and Eu(OTf)3 (0.024g, 0.04mmol) in anhydrous MeOH under Ar was stirred for 30min. To this was slowly added a solution of NaOH (1M in MeOH) such that the apparent pH was maintained at 5. The reaction mixture was then heated to 50C with constant stirring for 48h. After cooling the reaction mixture the solvent was evaporated under reduced pressure. The residue was dissolved in minimum amount of MeOH and re-precipitated by the gradual addition of ether. This dissolution/re-precipitation process was repeated several times and the light yellow solid mass was collected by filtration to give Ir?Eu in 60-70% yield.

As the paragraph descriping shows that 54761-04-5 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.54761-04-5,Ytterbium(III) trifluoromethanesulfonate,as a common compound, the synthetic route is as follows.

Under the protection of nitrogen atmosphere, the amount of organic solvent (for the volume ratio of 1: 0.2 of a mixture of polyethylene glycol and 15-crown-5) was added 100 mmol of the compound of formula (I) 250 mmol of the compound of formula (II) above, 9 mmol of catalyst (3 mmol Pd(dba)2) With 6mmol A mixture of ytterbium trifluoromethanesulfonate ,12 mmol oxidizer silver acetate and 30 mmol accelerator N-n-butyl-N-methylpiperidine bis(trifluoromethanesulfonyl)imide salt, and then the temperature was raised to 70 C, and the reaction was stirred at that temperature for 6 hours. After the reaction is complete, the filtrate is adjusted to adjust the pH of the filtrate to neutral and then saturated with hydrogen carbonate Sodium aqueous solution is fully shaken washing, adding dichloromethane extraction, separation of organic phase, and then Dried over anhydrous sodium sulfate, concentrated under reduced pressure, the residue over 200-300 mesh silica gel column chromatography, in vivo A mixture of petroleum ether and acetone having a ratio of 1: 3 was used as the eluent to give a compound of formula (III) And the yield was 93.9%., 54761-04-5

The synthetic route of 54761-04-5 has been constantly updated, and we look forward to future research findings.

54761-04-5, General procedure: ReBr(CO)3(N,N’-Phd-O,O’)Ln(OTf)3(THF) (III Y, Ln = Y; III Eu, Ln = Eu; III Yb, Ln = Yb) heterobimetallic complexes were synthesised by allowing 1.0 mmol (0.560 g) of fac-ReBr(CO)3(Phd) to react with 1.0 mmol of the respective anhydrous triflate salt Ln(OTf)3 in 20 mL of THF. After 72 h of stirring at ambient temperature, the solvent was evaporated under reduced pressure and diethyl ether (10 mL) was added. The solid thus separated was filtered, washed with a small amount of diethyl ether and dried.

General procedure: Compounds Ir6Ln (Ln=Eu, Tb, Er, Yb) were synthesized under similar optimized experimental conditions. A typical procedure for the preparation of [EuIr6(ppy)12(bpp)2(bppH)4](CF3SO3)¡¤18H2O (Ir6Eu) is described as below. Eu(CF3SO3)3 (0.0120g, 0.02mmol) was added to a methanol solution (5cm3) of [Ir(ppy)2(bppH)] (0.0135g, 0.02mmol). After heating the yellow solution at 100C under microwave irradiation for 30min, the filtrate was left to stand for one week at room temperature. Yellow block crystals were collected by suction filtration, washed with a minimum amount of methanol.
