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).
