Abstract

Nucleophilic addition to the (1-methylpentadienyl)Fe(CO)₂PPh₃⁺ cation proceeds predominantly at the substituted pentadienyl terminus to afford (5-substituted-1,3-(Z)-hexadiene)Fe(CO)₂PPh₃ products in very good yields. Decomplexation with Ce⁴⁺ generates the free ligand in good yields.

Addition of stabilized carbon nucleophiles to (1-methylpentadienyl)Fe(CO)₃PPh₃⁺ cation (2) proceeds predominantly at the substituted pentadienyl terminus to afford 5-substituted-1,3Z-hexadiene complexes (4). The ligand may be liberated by oxidation of the complex.
