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
71071-46-0, General procedure: A solution of compound 5 (400mg, 0.822mmol), [(eta6-p-cymene) RuCl2]2 (252mg, 0.411mmol), and Me4NCl (450mg, 4.11mmol) in anhydrous acetone (21mL) was stirred under a dark atmosphere at room temperature for 6h. The reaction mixture was filtered and the filtrate was evaporated to afford crude compound as a bright orange solid. The above intermediate (200mg, 0.373mmol), dimethyl 2,2?-bipyridine-4,4?-dicarboxylate (203mg, 0.746mmol), and potassium hexafluorophosphate (103mg, 0.56mmol) were dissolved in dry 1,2-dichloroethane (20mL) and the mixture was stirred at 60°C for 12h. The mixture was then concentrated under reduced pressure and the resulting crude product was purified by column chromatography using ethyl acetate/ dichloromethane (1:1) to give compound 6 as a dark red solid (233mg, 70percent). 1H NMR (300MHz, CDCl3): delta 8.89 (s, 1H), 8.85 (s, 1H), 8.79 (s, 1H), 8.74 (s, 1H), 8.39 (d, J=5.7Hz, 1H), 8.00?7.91 (m, 3H), 7.82 (m, 3H), 7.67 (dd, J=3.6Hz, 1.5Hz, 1H), 7.52 (dt, J=8.7Hz, 1.2Hz, 1H), 7.46 (d, J=7.5Hz, 1H), 7.32?7.19 (m, 5H), 7.13 (d, J=5.7Hz, 1H), 6.72 (dt, J=6.5Hz, 1.5Hz, 1H), 3.95 (s, 3H), 3.94 (s, 3H), 3.93 (s, 3H), 3.91 (s, 3H), 1.27 (s, 3H); 13C NMR (125MHz, CDCl3): delta 192.8, 164.6, 164.4, 164.2, 162.6, 157.9, 157.8, 156.5, 156.3, 155.6, 151.9, 151.4, 150.5, 149.8, 142.5, 142.4, 138.4, 137.3, 136.6, 135.6, 135.3, 135.0, 134.9, 129.4, 128.5, 127.9, 127.6, 126.3, 162.2, 125.8, 123.0, 122.9, 122.4, 120.4, 118.8, 53.6, 53.5, 53.4, 53.3, 15.5; HRMS (FAB):calcd. for C44H36N5O8RuS [M+] 896.1328, found 896.1321.
As the paragraph descriping shows that 71071-46-0 is playing an increasingly important role.
