With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.71071-46-0,Dimethyl [2,2′-bipyridine]-4,4′-dicarboxylate,as a common compound, the synthetic route is as follows.

71071-46-0, General procedure: A solution of cis-RuII(bpz)2Cl2 (100 mg, 0.205 mmol) and AgNO3 (77 mg, 0.453 mol) in water (25 mL) was heated at reflux for 48 h. After cooling to room temperature, the mixture was filtered through Celite to remove AgCl, and the filtrate was evaporated to dryness. The residue was dissolved in DMF (15 mL) and the solution purged with argon for 15 min. 4,4?-bis(trifluoromethyl)-2,2?-bipyridyl (121 mg, 0.414 mmol) was added and the mixture heated at 100 °C for 24 h under argon. After cooling to room temperature, the solution was evaporated under vacuum to a small volume and diethyl ether (150 mL) added. The precipitate was filtered off and dissolved in a minimum of cold water to which solid NH4PF6 was added. The solid was filtered off and purified by column chromatography as for 1 to give an orange solid. Yield: 73 mg (35percent).

The synthetic route of 71071-46-0 has been constantly updated, and we look forward to future research findings.

71071-46-0, Dimethyl [2,2′-bipyridine]-4,4′-dicarboxylate is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

A 1-liter, creased, 4-necked round bottom Pyrex flask equipped with mechanical stirrer, 250-milliliter (ml) addition funnel, temperature probe, heating mantle, and water-cooled total reflux condenser was used. The flask was initially charged with 200 grams (1.08 mole) of ADMA-10 (decyldimethylamine, available from Albemarle Corporation, Baton Rouge, LA), and 239 grams (1.08 mole) decyl bromide was placed in the addition funnel. The stirrer was turned on and the reactor was heated to 65C. The decyl bromide was added dropwise to the ADMA-10 as the temperature of the reactor was allowed to rise from 65C to 142C. The addition funnel was then charged with 110 grams of methanol, and the methanol was added dropwise to the solution as the temperature of the reactor was allowed to fall to 90C. After the entire volume of the methanol was added to the reaction mixture, the heat and stirring were ceased and the intermediate quaternary ammonium (quat-Br) solution was allowed to cool., 71071-46-0
