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
[Cu(CH3CN)4]ClO4 (16.3 mg, 0.050 mmol) was added to a mixtureof ppipH (19.3 mg, 0.050 mmol) and POP (27.9 mg, 98%,0.050 mmol) in DCM under a stream of dry argon with a vacuum-line system and Schlenk techniques and the mixture was stirredfor 2 h at room temperature. After filtration, layering n-hexanecarefully onto the DCM filtrate produced orange-yellow crystals afew days later as 1aCH2Cl2. The orange-yellow product wasobtained in a 55.4% yield (32.4 mg) after being dried under aninfrared lamp. Mp: 200.9-201.7 C. 1H NMR (400 MHz, DMSO-d6,d, ppm): 14.67 (s, 1H, NH), 9.07 (d, J = 8.0 Hz, 2H), 8.87 (d,J = 4.4 Hz, 2H), 7.93 (s, br, 2H), 7.45 (td, J = 7.6 Hz, J0 = 1.2 Hz, 2H),7.32-7.18 (m, 14H), 7.10 (t, J = 7.6 Hz, 2H), 7.00-6.96 (m, 8H),6.65-6.62 (m, 2H). 31P NMR (400 MHz, DMSO-d6, d, ppm):11.22. Characteristic IR spectrum (KBr, cm1): 3144 s (NH),1097 s (ClO4). ESI-MS (m/z): 987.1493 [Cu(ppipH)(POP)]+ (Calc.987.1497)., 166330-10-5
As the paragraph descriping shows that 166330-10-5 is playing an increasingly important role.
