1,1′‐Divinyl ferrocene (2) reacts with K3[Fe(CN)6] under basic biphasic conditions to give a [4]ferrocenophane (4) in good yield. Incorporating deuterium labels into the internal positions of the vinyl groups of 2 affects the chemoselectivity of the reaction; thus under identical reaction conditions, [D2]‐2 reacts to provide a diol‐functionalised [4]ferrocenophane, [D2]‐D/L‐6 in addition to the expected...
Lithium amides react with vinylferrocene in the presence of TMEDA to provide the corresponding (2-aminoethyl)ferrocenes in good to excellent yields. A range of secondary amines can be employed in this amidolithiation reaction, with cyclic derivatives affording particularly good yields of the 2-aminoethyl-substituted ferrocene product. This operationally simple procedure provides one of the most straightforward...
