In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 14871-92-2,(2,2¡ä-Bipyridine)dichloropalladium(II), as follows.14871-92-2
[Pd(bpy)Cl2] (0.10 g, 0.30 mmol) was suspended in water (4 mL). Lactic acid (0.03 g, 0.28 mmol) and 1 M NaOH (0.60 mL) were dissolved in water (10 mL) and then added to the mixture, which was heated under reflux at 150 C with continuous stirring until a clear yellow solution was obtained. The solution was filtered and acetone (10 mL) was added to the solution. The reaction mixture was cooled to 4 C for a long time (2 months), resulting yellow crystals of complex 5. Yield: 33%. m.p.: 250 C. Elemental Anal. Calc. for C13H13ClN2OPd (355.10): C, 44.0; H, 3.7; N, 7.9. Found: C, 44.1; H, 3.6; N, 7.8%. IR (KBr, numax/cm-1): 1634 s, nu(CO); 1621 s, nu(CC); 1496 m, 1443 s, nu(CC,CN). Far-IR (Nujol, numax/cm-1): 333 m, nu(Pd-Cl); 285 m, nu(Pd-C); 243 m, nu(Pd-N). 1H NMR (CDCl3, delta/ppm): 2.40 (s, 3H, c), 3.01 (s, 2H, a), 7.61 (m, 2H, 5,5?), 8.02 (m, 4H, 3,3? and 4,4?), 9.31, 9.51 (2d, 2H, 6,6?).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. 14871-92-2, We look forward to the emergence of more reaction modes in the future.
