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.
[Pd(bpy)Cl2] (.67 g, 2 mmol) was suspended in 200 mlacetone-water (3:1 v/v) and AgNO3 (.68 g, 4 mmol) wasadded with constant stirring. This mixture was heated at328 K with stirring in the dark for 6 h followed by stirringfor 16 h at room temperature. The AgCl precipitatewas removed by filtration using Whatman 42 filter paper.The clear yellow filtrate was mixed with mu-paraxylidinebisdithiocarbamatedisodium salt (.33 g, 1 mmol).The reaction mixture was subsequently stirred for 5 h at318 K and then filtered. The clear solution was concentratedto 5 ml at 318 K. The resulting yellow precipitatewas filtered and washed with small amounts of acetoneand resolved in 300 ml doubly distilled water at 318 K.The solution was filtered to remove turbidity. The clearsolution was then concentrated to 5 ml and refrigeratedovernight. The yellow precipitate was filtered and washedwith small amounts of cold distilled water and acetoneand dried in an oven at 318 K. The synthesis of the complexcan be summarized by Figure 1. Yield: .572 g(65%), Decomposition ranges: 520-523 K. Anal. Calcd.for C30H26N6S4Cl2Pd2: C, 40.86; H, 2.95, N, 9.53%.Found: C, 40.85; H, 2.96, N, 9.55%. Molar conductance,LambdaM (H2O, Omega-1 mol-1 cm2): 243. FT-IR (KBr pellets,cm-1): 1541 upsilon (C-N); 1022 upsilon (C-S) and 1385 (NO3- ion).UV-Vis data (water, lambdamax/nm (logepsilon): 308 (3.43), 247 (3.79) and 188 (3.95). 1H NMR (500 MHz, DMSO-d6,ppm, d = doublet, t = triplet and m = multiple): 7.66 (m,1H, H-a), 8.23 (m, 2H, H-b), 8.48 (d, 2H, H-c), 7.79(t, 2H, H-5,5), 8.30 (t, 2H, H-4,4), 8.57 (d, 2H, H-3,3),8.88 (d, 2H, H-6,6) (Figure S1).
The chemical industry reduces the impact on the environment during synthesis,14871-92-2,(2,2¡ä-Bipyridine)dichloropalladium(II),I believe this compound will play a more active role in future production and life.
