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, To a solution of complex Re1 (40 mg, 0.098 mmol) in hexane (1 mL), Ph2P(OEt) (25 mg, 0.109 mmol) was added. The reaction mixture was stirred for 2 h. The precipitate formed was filtered off and dried in oil-pump vacuum to yield 48 mg (77%) of product Re4 as light-yellow powder. Calculated for C29H26O3PRe, %: C, 54.45; H, 4.10. Found: C, 54.40; H, 4.12. IR (hexane), nu/cm-1: 1902s, 1835s (CO). 1H NMR (C6D6), delta: 0.89 (t, 3H, 3JHH = 7.0 Hz, OCH2CH3), 3.43 (dq, 2H, 3JHH ? 3JPH ? 6.4 Hz, POCH2CH3), 4.44 (s, 5H, Cp), 7.11-7.23 (Hpara Ph; Hmeta and Hpara PPh), 7.39 (dd, 2H, 3JHH = 7.6 Hz, Hmeta Ph), 8.02 (d, 2H, 3JHH = 7.9 Hz, Hortho PPh), 8.06 (d, 2H, 3JHH = 7.2 Hz, Hortho PPh), 8.37 (d, 2H, 3JHH = 7.7 Hz, Horhto Ph), 8.75 (d, 1?, 3JPH = 39.0 Hz, =CHPh). 31P{H} NMR (C6D6), delta: 32.28 (s, P+Ph2(OEt)).
As the paragraph descriping shows that 719-80-2 is playing an increasingly important role.
