  1. Subgroup – Vortrag Maria Eckhardt 28.06.11

  2. Analytik: FD - MS (Toluol): m/z = 943.8 [M+] 1H-NMR (C6D6, 400 MHz): δ[ppm] = 1.03 (s, 9H, C(CH3)3), 1.07 (s, 9H, C(CH3)3), 1.18 (s, 9H, C(CH3)3), 1.26 (s, 9H, C(CH3)3), 1.295 (s, 9H, C(CH3)3), 1.3 (s, 9H, C(CH3)3), 5.04 (pt, 3JHH = 2.72 Hz, 1H6, C5H3tBu2), 5.15 (pt, 3JHH = 2.72 Hz, 1H5, C5H3tBu2), 5.26 (t, 3JHH = 2.42 Hz, 1H4, C5H3tBu2), 6.99 (pt, J = 2.74 Hz, 1H3, C5H3tBu2), 7.09 (pt, J = 2.79 Hz, 1H2, C5H3tBu2), 7.26 (t, J = 2.54 Hz, 1H1, C5H3tBu2) 31P-NMR (C6D6, 161.98 MHz): δ[ppm] = -36.5 (d, 2JPP = 15.66 Hz, 1P), 68.5 (d, 2JPP = 15.45 Hz, 1P)

  3. Möglicher Bildungsweg

  4. ? Über Nacht rühren → weißer, gelblicher NS NS unlöslich in Toluol, THF und CH2Cl2 Lsg filtrieren → NMR: im 31P-NMR nur Peaks für Cp''2ZrP4, im 1H-NMR allerdings Cp''2ZrCl2 ? Über Nacht rühren → optisch keine Veränderung wahrnehmbar NMR → keine Reaktion
