855-38-9, Tris(4-methoxyphenyl)phosphine is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,855-38-9
A mixture of [{(mu-SCH2)2CH2}Fe2(CO)6] (0.193 g, 0.5 mM), P(PhOMe-p)3 (0.211 g, 0.6 mM), and Me3NO¡¤2H2O (0.056 g, 0.5 mM) was dissolved in MeCN (15 mL) and was stirred at room temperature for 2 h to give a black-red solution. The solvent was removed on a rotary evaporator and the residue was subjected to preparative TLC separation using CH2Cl2/petroleum ether (v/v = 1 : 5) as eluent. From the main red band, 1 (0.241 g, 68%) was obtained as a red solid. M.p.: 180-181 C. Anal. Calcd for C29H27Fe2O8PS2: C, 49.04; H, 3.83%. Found: C, 48.93; H, 3.99%. IR (KBr disk, cm-1): nuC?O 2041 (vs), 1985 (vs), 1979 (vs), 1958 (vs), 1930 (vs). 1H NMR (400 MHz, CDCl3, TMS, ppm): 7.58 (t, 3JHH = 3JHP = 7.6 Hz, 6H, PhH), 6.93 (d, 3JHH = 7.6 Hz, 6H, PhH), 3.84 (s, 9H, OCH3), 1.78-1.72 (m, 2H, SCHaHe), 1.54-1.48 (m, 4H, SCHaHe and CH2). 13C{1H} NMR (100.6 MHz, CDCl3, TMS, ppm): 213.92 (d, 2JPC = 12.0 Hz, PFeCO), 209.83 (s, FeCO), 160.97 (s, ipso-PhCOMe), 134.97 (d, 2JPC = 12.3 Hz, o-PhCH), 127.55 (d, 1JPC = 44.8 Hz, ipso-PhCP), 114.00 (d, 3JPC = 10.5 Hz, m-PhCH), 55.37 (s, OCH3), 30.02 (s, CH2), 22.29 (s, SCH2). 31P{1H} NMR (161.9 MHz, CDCl3, 85% H3PO4, ppm): 60.26 (s).
The synthetic route of 855-38-9 has been constantly updated, and we look forward to future research findings.
