128143-89-5, 4′-Chloro-2,2′:6′,2”-terpyridine is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

28 mg (<5 mol %) of zinc(II) chloride and 4.4 g (61.5 mmol) of pyrrolidine are added in succession to a mixture of 1.1 g (4.1 mmol) of 4-chloro-[2,2';6',2]terpyridine in 15 ml of 2-methyl-2-butanol. The mixture is heated at reflux for 20 hours, cooled and filtered. Pure 4'-pyrrolidin-1-yl-[2,2';6',2]terpyridine is obtained in the form of a white solid after recrystallisation from toluene. MS (EI, 70 eV): m/z=303 (15); 302 (90, [M+]); 273 (100); 233 (25). 1H-NMR (360 MHz, CDCl3): 1.9-2.0 (m, 4H); 3.39-3.49 (m, 4H); 7.18 (dd, 2H, J=6.7, 5.2 Hz); 7.51 (s, 2H); 7.66-7.76 (tm, 2H); 8.51 (d, 2H, J=7.7 Hz); 8.54-8.60 (m, 2H). 128143-89-5, As the paragraph descriping shows that 128143-89-5 is playing an increasingly important role.

128143-89-5, 4′-Chloro-2,2′:6′,2”-terpyridine is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

To a stirred solution of 40-Cltpy (26.7 mg, 0.100 mmol) in CH2Cl2(10 cm3) was added dropwise a methanolic solution (5 cm3) ofCoCl26H2O (23.7 mg, 0.100 mmol) at room temperature, theresulting green solution was stirred for 10 min, then filtered. Thefiltrate was allowed to slowly evaporate at room temperature for3 days, during which time green plates had formed and werecollected by decanting the solvent, washed with methanoland dried in air. Yield: 32.5 mg (81.7%). FT-IR (solid, cm1):1590s, 1553s, 1469s, 1415s, 1340w, 1290w, 1245 m, 1118s,1051w, 1016s, 898 m, 830s, 793s, 726 m, 687w, 634 m. Anal.Calc. C15H10Cl3CoN3 (397.55) requires: C, 45.32; H, 2.54; N, 10.57.Found: C, 45.33; H, 2.60; N, 10.54%.

The synthetic route of 128143-89-5 has been constantly updated, and we look forward to future research findings.
