The iron complex [Fp][OTf] Fp+ = [Fe(CO)2(Cp)]+, OTf– = SO3CF3–} is an efficient catalyst for the direct substitution of the OH group in ferrocenylmethanol [Fc–CH2OH] by thiols, aromatic amines, diphenylphosphane, and carbon nucleophiles (furan, pyrrole, and indole). This approach offers a convenient route to ferrocenes containing side chains with different functional groups. The advantages of the
