With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.17217-57-1,4,4′-Dimethoxy-2,2′-bipyridine,as a common compound, the synthetic route is as follows.

General procedure: [Cu-(MeCN)4]PF6 (74 mg, 0.20 mmol) was added to TolBINAP(135 mg, 0.20 mmol) in 2 mL CH2Cl2. Then, bpy (31 mg, 0.20mmol) was added. The yellow reaction mixture was stirred for90 minutes at room temperature. Diethyl ether (25 mL) wasadded to the solution to precipitate the product as a yellowsolid, which was filtered and dried in vacuum.

17217-57-1, 4,4′-Dimethoxy-2,2′-bipyridine is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

General procedure: Heteroleptic iridium 4xy were synthesized in a two-step procedure[42,43]. In the first step, chloro-bridged dimer was synthesized by charging a two-necked reaction flask with magnetic stir bar, iridium(III) chloride (1 equiv), ligand (2.26 equiv), and a 2:1 v:v mixture of 2-methoxyethanol/water. The mixture was degased with Ar (via Ar bubbling) and heated under reflux at 120 ¡ãC with constant stirring overnight. The reaction mixture cooled to room temperature and filtered. The precipitate was washed with water (3×10 mL), dried in air and taken onto the second step without further purification unless noted. In the second step, the chloro bridging dimer (1 equiv), bipyridyl ligand (2.2 equiv) and ethylene glycol were placed in a two-necked flask and then flushed with Ar. The mixture was heated at 150 ¡ãC for 15 h and then cooled. The cooled reaction mixture was washed hexane (3 10 mL) and mixture was heated to 85 ¡ãC for 5 min to remove residual hexane. Aqueous ammonium hexafluorophosphate (sat. solution) was added to the reaction mixture causing the iridium-PF6 salt to precipitate,which was filtered, dried and recrystallized (acetone/ether).

General procedure: 4,4?-Dmo-2,2?-bpy (0.22 g, 1 mmol) was placed in oneof the arms of a branched tube [32], and zinc(II) acetatedihydrate (0.11 g, 0.5 mmol) and potassium thiocyanate(0.10 g, 1 mmol) were placed in the other arm. Ethanoland water in a ratio of 3:2 were carefully added to fill botharms. The tube was then sealed and the ligand-containingarm was immersed in a bath at 60¡ãC, whereas the otherwas maintained at ambient temperature. After 1 day, crystalsthat were deposited in the cooler arm were filtered off,washed with mother liquid, and dried in air, yield: 0.18 g,59percent.
