Some tips on 14871-92-2

As the paragraph descriping shows that 14871-92-2 is playing an increasingly important role.

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.

General procedure: Palladium(II) chloride (PdCl2), 2,2?-bipyridine (bipy), 1,10-phenanthroline (phen), thiourea (TU, 1), N-methylthiourea (meTU, 2), N-buthylthiourea (buTU, 3), N,N?-diethylthiourea (dietTU, 4) and N,N?-dibuthylthiourea (dibuTU, 5) were purchased as pure reagents at AG, from Sigma Aldrich. Potassium tetrachloropalladate(II) was prepared by the reaction of palladium chloride with a slight excess of potassium chloride. The complexes [Pd(bipy)Cl2] and [Pd(phen)Cl2], were obtained by adding 1 mmol of the respective ligand to 0.326 g (1 mmol) of K2[PdCl4] suspended/dissolved in 40 mL of wet methanol under reflux for about 1 h. The precipitated crystalline powders were recovered by filtration and dried under vacuum for 2 h. 0.25 mmol of these complexes (83 and 89 mg, respectively) were then suspended again in a water/methanol mixture, whereupon 0.5 mmol of the respective thiourea (1-5) was added under reflux. After 1 h, clear yellow to orange solutions were obtained. These solutions were filtrated and the filtrates were kept for 3-5 days at room temperature for crystallization. As a result yellow-red crystals were obtained. The experimental yield of the products, based on Pd, was more than 50%. All the solvents, of analytical grade, were dried and deoxygenated before being used. Elemental analyses were performed at the Microanalytical Laboratory of Redox snc (Milano). Characterization details are extensively quoted in the supplementary material.
