18437-78-0, Tris(4-fluorophenyl)phosphine is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To 20 mL methanolic suspension of palladium(II) chloride (0.177 g,1 mmol) in a round bottom three-neck flask was added tris(4-fluorophenyl)phosphine (0.316 g, 1 mmol) solution in acetone (20 mL) and sodium 4-(3-methoxyphenyl)piperazine-1-carbodithioate (0.290 g, 1 mmol) solution in methanol (30 mL) in a dropwise manner.The reaction mixture was refluxed for 6 h with constant stirring. The formed greenish precipitate was separated by filtration (scheme 1). This precipitate was re-dissolved in acetone, and on slow evaporation, needle crystals were obtained.Yield: (0.470 g, 60percent), m.p. 250 ¡ãC. Mol. Wt: 745.48: Anal.
