The reactivity of squarylferrocenes was studied in the addition of several N-centered nucleophiles. A total of seven simple amines (primary and secondary) were added to both monosquarylferrocene and 1,1?-bissquarylferrocene to generate 14 ferrocenylsquaramides in 85-98%. Likewise, five aminoesters were added to the same scaffolds to produce a novel family of 10 ferrocene-aminoester conjugates in good to excellent yields (57-95%).
