With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.7650-91-1,Benzyldiphenylphosphine,as a common compound, the synthetic route is as follows.
7650-91-1, A mixture of Fe2(l-pdt)(CO)6 (0.097 g, 0.25 mmol), Ph2P(CH2Ph) (0.083 g, 0.3 mmol) and Me3NO2H2O (0.034 g, 0.3 mmol) was dissolved in MeCN (15 mL). The mixture was stirred at room temperature for 0.5 h to give a brown-red solution. The solvent was removed on a rotary evaporator and the residue was subject to preparative TLC separationusing CH2Cl2/petroleum ether (v/v1:5) as eluent. From the main red band, 1(0.076 g, 48%) was obtained as a red solid. Anal. Calcd for C27H23Fe2O5PS2: C, 51.13; H,3.66%. Found: C, 50.95; H, 3.87%. FT-IR (KBr disk, cm-1): mCO 2041 (vs.), 1979 (vs.),1954 (s), 1922 (m). 1H NMR (600 MHz, CDCl3, TMS, ppm): 7.68 (s, 4H, 2xPPhH-o), 7.44 (s,6H, 2xPPhH-m,p), 7.17 (s, 1H, CH2PhH-p), 7.11 (s, 2H, CH2PhH-o), 6.71 (s, 2H, CH2PhHm),3.87 (s, 2H, CH2Ph), 1.86 (s, 2H, 2xSCHeHa), 1.65-1.51 (m, 2xSCHeHa and CH2).31P{1H} NMR (243 MHz, CDCl3, 85% H3PO4, ppm): 63.14 (s).
As the paragraph descriping shows that 7650-91-1 is playing an increasingly important role.
