It is a common heterocyclic compound, the catalyst-palladium compound, (2,2¡ä-Bipyridine)dichloropalladium(II), cas is 14871-92-2 its synthesis route is as follows.
Pd(2,2?-bpy)Cl2 (67 mg, 0.2 mmol) was stirred with AgNO3 (68 mg, 0.4 mmol) in water (10 mL) with light excluded at 40 C for 12 h. The suspension obtained was cooled to 0 C in ice bath for 30 min. Then AgCl was removed from the solution by filtration. 1 (52.8 mg, 0.2 mmol) was added to the clear filtrate and pH was measured and found to be 2.0. Then the mixture was stirred at 40 C for 2 h. The resulting light yellow solution was concentrated to a volume of 5 mL at 40 C on a rotary evaporator. Yellow cubes were obtained after one day. The yield was 85 mg (60%). 1H NMR (D2O, pD 2.0, 298 K, delta, ppm): 1?, 3.69 (12 H, s, CH3), 3.60 (4H, s, CH2), 7.93 (4H, s, H6); 2,2?-bpy, 7.23 (4H, dd, H5, 3JH-H = 6.0 Hz, 4JH-H = 3.0 Hz), 7.60 (4H, t, H5?, 3JH-H = 7.2 Hz), 7.79 (4H, dd, H6, 3JH-H = 6.0 Hz), 7.94-8.18 (20H, m, H3,H3?,H4,H4?,H6?).
14871-92-2, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,14871-92-2 ,(2,2¡ä-Bipyridine)dichloropalladium(II), other downstream synthetic routes, hurry up and to see
