13440-07-8, Di(naphthalen-1-yl)phosphine oxide is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Solution of di(1-naphthyl)phosphine oxide (0.1 g) in chloroform (5 mL) was refluxed in air for 2 h. Then the solvent was distilled under reduced pressure and residue was dried in vacuum. Di(1-naphthyl)phosphinic acid was prepared in near quantitative yield. White powder, mp 198-201 C, FT-IR (KBr): 3055, 3008, 2955, 2922, 2854, 2632, 2289, 1955, 1646, 1619, 1591, 1568, 1505, 1456, 1432, 1382, 1334, 1212, 1178, 1152, 1025, 995, 951, 833, 800, 773, 753, 680, 566, 526, 479. 1H NMR (CDCl3): 9.58 (br, 1H, OH), 8.48 (d, J 8.5 Hz, 2H, H8), 8.16 (dd, J 16.3 and 7.2 Hz, 2H, H2), 7.92 (d, J 8.4 Hz, 2H, H4), 7.79 (d, J 8.1 Hz, 2H, H5), 7.40-7.36 (m, 4H, H6,7), 7.29 (t, J 7.7 Hz, 2H, H3). 13C NMR (CDCl3): 133.5 (d, J 11 Hz, C9), 133.4 (d, J 11 Hz, C8), 133.3 (d, J 2 Hz, C7), 132.7 (d, J 11 Hz, C10), 128.9 (d, J 137 Hz, C1), 128.7 (C4), 127.1 (C5), 126.6 (d, J 5 Hz, C3), 126.1 (C6), 124.5 (d, J 15 Hz, C2). 31P NMR (CDCl3): 37.3 ppm. MS m/z calcd for C20H15O2P: MS (M+ 315)., 13440-07-8
The synthetic route of 13440-07-8 has been constantly updated, and we look forward to future research findings.
