24171-89-9, Tri(thiophen-2-yl)phosphine is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A toluene (50 mL) solution of Ru3(CO)12 (200 mg, 0.31 mmol) and PTh3 (88 mg, 0.31 mmol) was refluxed for 10 min during which time the color changed from yellow to orange. The solvent was removed under reduced pressure and the residue was subjected to TLC on silica gel. Elution with hexane/CH2Cl2 (9:1, v/v) gave several bands. The first band gave 1 (15 mg, 6%) while the second band gave Ru3(CO)9{mu-Th2P(C4H2S)}(mu-H) (4) (65 mg, 25%) as orange crystals after recrystallization from hexane/CH2Cl2 at 4 C. Anal. Calcd for C21H9O9P1Ru3S3: C, 30.18; H, 1.09%. Found: C, 30.35; H, 1.12%. IR (nuCO, CH2Cl2): 2085 s, 2060 s, 2034 s, 2022 s, 2014 m, 1998 w cm-1. 1H NMR (CDCl3): delta 7.61 (m, 1H), 7.43 (m, 1H), 7.72 (m, 1H), 7.32 (m, 2H), 7.23 (m, 2H), 7.16 (m, 2H), -17.70 (d, J = 20.5 Hz, 1H). 31P{1H} NMR (CDCl3): delta 17.82 (s, 1P). FAB MS: m/z 837 (M+). The third band afforded Ru3(CO)8{mu-Th2P(C4H2S)(PTh3)(mu-H) (5) (26 mg, 8%) as pink crystals from hexane/CH2Cl2 at 4 C. Anal. Calcd for C32H18O8P2Ru3S6: C, 35.32; H, 1.67%. Found: C, 35.50; H, 1.70%.
