With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.14871-92-2,(2,2¡ä-Bipyridine)dichloropalladium(II),as a common compound, the synthetic route is as follows.
[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 synthetic route of 14871-92-2 has been constantly updated, and we look forward to future research findings.
