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,128143-89-5
was added to a stirred suspensionof KOH (1.05 g, 18.7 mmol) in anhydrous DMSO(20 mL) at 60 C. After 60 min, 40-chloro-2,20:60,200-terpyridine (1.00 g, 3.7 mmol) was added to the mixture,which was maintained with stirring for 4 h at 70 C. Distilledwater (600 mL) was then added to the reaction mixture,and the product was extracted with CH2Cl2(3 ¡Á 200 mL). Residual water in the CH2Cl2 was removedusing Na2SO4, and the CH2Cl2 was removed using a rotaryevaporator. The desired product was recrystallized fromethyl acetate to give 0.72 g (72%) of 4. 1H NMR(300 MHz, CDCl3-d) 8.7 (d, 2H, J = 4.7 Hz), 8.6 (d, 2H,J = 7.4 Hz), 8.0 (m, 4H), 7.5 (m, 2H), 4.0 (m, 2H), 3.2(dd, 1H, J = 6.3 Hz and J = 12.5 Hz) 1.7 (s, 2H), 1.1 (d,3H, J = 6.4 Hz). 13C NMR (125 MHz, CDCl3-d) 160.2,156.5, 154.2, 148.9, 123.7, 120.8, 105.2, 70.1, 48.1, 21.4.ESI-MS (m/z) calcd. For C18H18N4O: 306.2; 307.307[M + H]+. Elemental analysis: calculated for C18H18N4O:C 70.6, H 5.9, N 18.3. Found: C 70.2, H 5.5, N 18.1.
