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.

The mixture was stirred at 60 C for 24 hrs, and the white AgCl precipitate was filtered by a short pad of celite. The filtrate was sampled for ESI-HRMS, and cationic C20H18N4O2Pd22+ (m/z: 279.9743) was observed. Then the filtrate was concentrated and recrystallized to give 25 mg light yellow needle-like solid. Yield 9.0%.

This compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,14871-92-2,(2,2¡ä-Bipyridine)dichloropalladium(II),its application will become more common.

General procedure: To a stirred suspension of [Pd(bpy)Cl2] (0.03 g, 0.1 mmol) or[Pd(phen)Cl2] (0.04 g, 0.1 mmol) in MeOH (10 mL) a solution ofHhmbt (0.023 g, 0.1 mmol) in MeOH containing KOH (0.006 g,0.1 mmol; 10 mL) was added drop by drop with stirring. The reactionmixture was warmed for 48 h, upon which a yellow-orangeprecipitate was filtered off, washed with MeOH, Et2O and driedin vacuo.For[Pd(bpy)(hmbt)]Cl2H2O: Yield: 0.07 g (51%).
