719-80-2, Ethoxydiphenylphosphine is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
719-80-2, General procedure: To a solution of [Fe2(CO)6(m-SCH2CH2CH2S)] (0.039 g, 0.10 mmol) and methyl diphenylphosphinite(0.022 g, 0.10 mmol) in CH2Cl2 (5 mL) was added a solution ofMe3NO2H2O (0.011 g, 0.10 mmol) in MeCN (5 mL). The mixture was stirred at roomtemperature for 1 h and then the solvent was reduced on a rotary evaporator. Theresidue was subjected to TLC using CH2Cl2/petroleum ether 1:5 (v/v) as eluent.From the main red band, 0.045 g (78%) of 2 was obtained as a red solid. IR (CH2Cl2,cm1): mCO 2045 (vs), 1983 (vs), 1933 (m). 1H NMR (500 MHz, CDCl3): 7.78 (s, 4H, PhH),7.45 (s, 6H, PhH), 3.61 (d, J12.5 Hz, 3H, CH3), 1.88 (s, 2H, CH2), 1.63 (s, 4H, 2SCH2)ppm. 31Pf1Hg NMR (200 MHz, CDCl3, 85% H3PO4): 167.75 (s) ppm. 13Cf1Hg NMR(125 MHz, CDCl3): 213.67 (d, JP-C 13.7 Hz, PFeCO), 209.61 (s, FeCO), 139.22 (d, JP-C 42.9 Hz, i-PhC), 131.07 (d, JP-C 12.2 Hz, o-PhC), 130.73 (s, p-PhC), 128.43 (d, JP-C 9.7 Hz, m-PhC), 53.16 (s, CH3), 30.09 (s, SCH2), 22.01 (s, CH2) ppm. Anal. Calcd. forC21H19Fe2O6PS2: C, 43.93; H, 3.34. Found: C, 44.06; H, 3.52%.
The synthetic route of 719-80-2 has been constantly updated, and we look forward to future research findings.
