General procedure: 2,2′-bipyridine (0.025 g, 0.16 mmol) was dissolved in DCM:MeOH 2:1 (6 mL) and [Ir(pyba)2(Cl)]2 (0.100 g, 0.08 mmol) was added. The mixture was heated at reflux under nitrogen atmosphere,in the dark. After 6 h, the yellow solution was cooled to room temperature. The crude solid was purified by column on silicaeluted with MeCN:H2O:KNO3 7:1:0.5. The yellow fractionwas driedunder vacuum, redissolved in acetonitrile and filtered. The solutionwas dried again and the solidwas dissolved in a minimal amount ofmethanol and NH4PF6 (130 mg, 0.9 mmol) was added allowed tostir overnight. The solution was left in the fridge for two hours,recrystallised with ether and then filtered on sintered glass. Ayellow powder was collected by filtration. (42 mg, yield 30%), 18511-72-3

18511-72-3 4,4-dinitro-2,2-Bipyridine 11519563, acatalyst-ligand compound, is more and more widely used in various fields.
