166330-10-5, (Oxybis(2,1-phenylene))bis(diphenylphosphine) is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
D1 (0.12 g, 0.4 mmol), copper powder (0.032 g, 0.5 mmol), and POP (0.22 g, 0.4 mmol) werereacted in CH3CN (5 mL) at 60 ¡ãC for 24 h. The resulting mixture was filtered through a plugof Celite and concentrated to 1 mL. Addition of Et2O (10 mL) to the filtrate afforded a paleyellow precipitate, which was collected, washed with Et2O, and recrystallized with ethanol.Yield: 0.29 g, 80percent. 1H NMR (400 MHz, DMSO) delta (ppm): 8.32 (s, 1H), 8.02 (t, J = 6.4 Hz, 3H), 7.53(s, 1H), 7.43?7.37 (m, 5H), 7.33 (d, J = 6.9 Hz, 5H), 7.26 (d, J = 6.7 Hz, 4H), 7.17?7.05 (m, 9H), 6.92 (s, 4H), 6.66 (s, 2H), 3.44 (s, 3H); 13C NMR (101 MHz, DMSO) delta (ppm): 157.93, 148.14,140.51, 133.66, 132.91, 132.38, 132.10, 131.80, 131.61, 131.42, 129.82, 128.73, 125.00, 124.72,123.83, 122.44, 120.47, 116.92, 112.23, 37.52; 31P NMR (162 MHz, DMSO) delta (ppm): ?8.80 (s),?143.57 (quint). HRMS (m/z, ESI+): Calcd for C45H37CuN3OP2 ([M]+) 760.1708; found 760.1723.Anal. Calcd for C45H37CuF6N3OP3 (906.25): C, 59.64; H, 4.12; N, 4.64. Found: C, 59.97; H, 4.47;N, 4.52., 166330-10-5
The synthetic route of 166330-10-5 has been constantly updated, and we look forward to future research findings.
