With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.15529-49-4,Dichlorotris(triphenylphosphino)ruthenium (II),as a common compound, the synthetic route is as follows.
A mixture of [RuCl2(PPh3)3] (166.8 mg, 0.1740 mmol) and amide-LH2 (68.8 mg, 0.168 mmol) in dichloromethane (10 mL) was stirred for 16 h at room temperature. After removal of the solvent, recrystallization from THF-hexane (5 mL/15 mL) afforded 2b¡¤2THF¡¤hexane as red crystals. The thoroughly dried sample was found to lose the solvating molecules on the basis of 1H NMR spectroscopy and combustion analysis. Yield: 156.8 mg (0.07088 mmol, 84%). 1H NMR (CDCl3): delta 1.18 (s, 36H, CMe3), 6.91 (t, 24H, J = 7.5, PPh3), 7.04 (d, 4H, 4JHH = 2.2, pyrazole CH), 7.13 (t, 12H, JHH = 7.0, PPh3), 7.21 (d, 4H, 3JHH = 7.7, 3- and 5-C5H3N), 7.30-7.34 (m, 24H, PPh3), 7.59 (t, 2H, 3JHH = 8.0, 4-C5H3N), 10.33 (br s, 4H, NH), 12.41 (br d, 4H, 4JHH = 2.4, NH). 31P{1H} NMR (CDCl3): delta 35.3 (s). IR (KBr): 1687 cm-1 (C=O). Anal. Calc. for C114H114Cl4N14O4P4Ru2: C, 61.90; H, 5.19; N, 8.86. Found: C, 62.18; H, 5.44; N, 8.51%., 15529-49-4
