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
Complex 1 was synthesized by the simultaneous and dropwise addition of tris-(4-fluorophenyl)phosphine(0.316 g, 1 mmol) in acetone and sodium 4-benzylpiperazine-1-carbodithioate (0.274 g, 1 mmol)in methanol to a methanolic suspension of palladium(II) chloride (0.177 g, 1 mmol). The reaction mixturewas refluxed for 5 h with constant stirring. The resulting orange-colored solution was filtered androtary evaporated to obtained orange solid (scheme 1). It was dried and re-dissolved in chloroform,and on slow evaporation needle-like crystals were obtained. Complexes 2 and 3 were synthesized bythe same method (scheme 1). Complex 1: Yield: 0.50 g (65percent), M.p. 198 ¡ãC. Mol. Wt: 709.47: Anal. Cald (found) for C30H27ClF3N2PPdS2:C, 50.78 (50.71); H, 3.84 (3.83); N, 3.95 (3.92); S, 9.04 (9.00): IR (4000?200 cm?1): 1492 v(C?N); 1010 v(CSSsym);378 v(Pd?S); 303 v(Pd?Cl); 245 v(Pd-P). 1H NMR {CDCl3, 300 MHz, delta (ppm)}: 3.40 (s, 2H, H4), 3.56 (t, 4H,H2, H2?, 3J1H, 1H = 5.1 Hz), 2.27 (t, 4H, H3, H3?, 3J1H, 1H = 5.1 Hz), 7.28?7.40 (m, 17H, H6, H6?, H7, H7?,H8, Hb, Hb?,Hc, Hc?). 13C NMR {CDCl3, 75 MHz, delta (ppm)}: 205.4 (C1); 51.8 (C2, C2?), 46.8 (C3, C3?); 62.5 (C4), 136.8 (C5),129.1 (C6, C6?), 128.2 (C7, C7?), 127.6 (C8), 163.2 (Ca), 115.9 (Cb, Cb?); 124.8 (Cc, Cc?), 165.7 (Cd).
