14871-92-2, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. (2,2¡ä-Bipyridine)dichloropalladium(II), cas is 14871-92-2,the catalyst-palladium compound, it is a common compound, a new synthetic route is introduced below.
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%).
