607-01-2, Ethyldiphenylphosphine is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To acetone solution of (diphenylphosphino) ethane (dppe) (0.398 g, 1 mmol) was added 4-nitrophenacyl bromide (0.256 g, 1.05 mmol)and the resulting mixture was stirred for 12 h at room temperature. The resulting yellow solution was filtered off, washed with petroleum diethyl ether, and dried under vacuum. Yield: 0.49 g, 75%; m. p.:220-222 C. Anal. Calc. for C34H30BrNO4P2: C, 62.02; H, 4.59; N, 2.13. Found: C, 62.27; H, 4.61; N, 2.15%. Selected IR absorption in KBr (cm-1): 1684 (nuC=O), 1191 (nuP=O). 31P{1H} NMR (CDCl3): deltaP = 19.45 (d, PCH2, 3JPP = 58.37); 31.66 (d, P(O)Ph2, 3JPP = 54.82). 1H NMR (CDCl3): deltaH = 2.83 (m, 2H, CH2); 3.82 (m, 2H, CH2); 6.32 (d, 1H, PCH2CO, 2JPH = 12.25), 6.52 (d, 1H, PCH2CO, 2JPH = 12.00); 7.18-8.37 (m, 24H, Ph). 13C{1H} NMR (CDCl3): deltaC = 18.06 (t, CH2, 1JPC = 26.03); 36.32 (pseudot, PCH2CO, 1JPC = 29.13); 116.03-134.95 (Ph); 191.31 (s, CO).
607-01-2, Big data shows that 607-01-2 is playing an increasingly important role.
