Name is Aminoferrocene, as a common heterocyclic compound, it belongs to iron-catalyst compound, and cas is 1273-82-1, its synthesis route is as follows.,1273-82-1
(Aminoferrocenyl)(ferrocenyl)carbene(pentacarbonyl)tungsten(0) (W(CO)5(E-2)): 402 mg (2.0 mmol) of Fc-NH2 and 1132 mg (2.0 mmol) of W(CO)5(1Et) where dissolved in dryTHF (40 mL). 1595 mg (8.0 mmol) of potassium hexa methyldisilazide(KHMDS) in dry THF (40 mL) were added with in 5.5 h while stirring at room temperature. The reaction was monitored by TLC to check the reaction progress and to stopthe reaction before extensive imine formation occurs. After 8 h,the solvent was removed under reduced pressure and anaqueous saturated NaHCO3 solution (100 mL) was added.The aqueous phase was extracted with dichloromethane(3 ¡Á 100 mL) and the combined organic phases were washed with aqueous saturated NaHCO3 solution (2 ¡Á 100 mL) and brine (2 ¡Á 100 mL). The organic phase was dried over MgSO4. After evaporation of the solvent under reduced pressure, a crudered product was obtained (1.04 mg). Purification by columnchromatography (SiO2; 40 cm ¡Á 5.5 cm; petroleum ether (40/60):CH2Cl2 1:1; Rf (Fc-NH2) = 0.0, Rf (E-3) = 0.5,Rf (W(CO)5(E-2)) = 0.8) yielded 403 mg (0.56 mmol, 28%) of deep red crystalline needles. 1H NMR (CD2Cl2): delta 10.50 (s, 1H,H6), 4.73 (pt, 2H, H8), 4.71 (pt, 2H, H3), 4.62 (pt, 2H, H2),4.37 (s, 5H, H1/10), 4.33 (pt, 2H, H9), 4.32 (s, 5H, H1/10) ppm; 13C NMR (CD2Cl2) delta 259.6 (C5), 204.4 (C12), 199.3(C11,1JWC = 127 Hz), 99.7 (C7), 97.7 (C4), 72.1 (C2), 70.7(C3), 70.6 (C1/10), 70.2 (C1/10), 69.1 (C8), 67.8 (C9) ppm; MS(FD) m/z (int.): 721.0 (100, [M]+); IR (KBr) : 3335 (m, NH),3107 (s, CH), 2058 (vs, CO), 1977 (vs, CO), 1899 (br, CO),1508 (s), 1350 (m), 1238 (m), 1057 (m), 822 (m), 600 (s), 579(m), 480 (m) cm-1; IR (CH2Cl2) : 2060 (vs, CO A1), 1975 (s,CO B1), 1921 (br, CO E, A1), 1503 (m) cm-1; IR (CD2Cl2) :3439 (w, NH(W(CO)5(Z-2))), 3240 (m, NH(W(CO)5(E-2)))cm-1; UV-vis (CH2Cl2) lambdamax (epsilon): 290 sh (15370), 355 (11020),387 (11680), 468 sh (2570 M-1 cm-1) nm; CV (THF, vs FcH/FcH+): E1/2 = -2.38 V (qrev.), Ep,ox = 0.26, 0.48 V, Ep,red =0.17, -0.15, -0.76 V; Anal. calcd for C26H19Fe2NO5W (720.95): C, 43.31; H, 2.66; N, 1.94; found: C, 43.30; H, 2.69;N, 1.91.
With the complex challenges of chemical substances, we look forward to future research findings about Aminoferrocene
