文摘

Aluminum compounds with up to four ferrocenyl groups (Fc) linked to aluminum were prepared and characterized in solution by NMR spectroscopy (¹H, ¹³C, ²⁷Al NMR), and in one case, tri(ferrocenyl)aluminum-pyridine Fc₃Al-py in the solid state by X-ray structural analysis. The attempts to stabilize the unsymmetrical species R₂Al-Fc and RAl(Fc)₂ (R = Me, Et) as the pyridine adducts were partially successful, although it proved difficult to suppress the formation of species containing Al–Cl functions completely.
