Versatile reactivity of amines towards the ruthenocenylmethylium cation [Cp*Ru(C5Me4CH2)]+

The cationic complex [Cp*Ru(C₅Me₄CH₂)]⁺ reacts with Et₃N primarily giving the ammonium salt [Cp*Ru(C₅Me₄CH₂NEt₃)]⁺. The prolonged standing of the reaction mixture results in the formation of the ether Cp*Ru(C₅Me₄CH₂OCH₂C₅Me₄)RuCp*. The reaction of [Cp*Ru(C₅Me₄CH₂)]⁺ with PhNEt₂ leads to the electrophilic aromatic substitution product [Cp*Ru(C₅Me₄CH₂C₆H₄NHEt₂)]⁺.
