14871-92-2, (2,2¡ä-Bipyridine)dichloropalladium(II) is a catalyst-palladium compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A suspension of 1 mmol (0.333 g) of [Pd(bpy)Cl2] in 150 mL ofacetone was treated with 1 mmol (0.228 g) of benzyl dithiocarbamatesodium salt and the mixture was refluxed under continuousmagnetic stirring for 2 h. Stirring continued for another 12 h at 318 K and then filtered.The resulting yellow colored filtrate containing the desired productwas concentrated to 15 mL at 318 K. The orange precipitate formedwas filtered off and washed with diethyl ether. Recrystallizationwas done by dissolving the precipitate in minimum amount ofethanol. Yield: 0.336 g (70%) and decomposes at 207-209 C. Anal.Calcd. for C18H16N3S2ClPd (480.34 g mol-1) Found, (Calcd.) (%): C45.01, (45.05); H, 3.36 (3.34); N, 8.75 (8.76).
