The cationic aniline complex [Cp*Rh(η6-2,6-(Me2CH)2C6H3NH2)](OTf)2 (1) was prepared from either [Cp*Rh(η2-NO3)(η1-OTf)] or [Cp*Rh(OH2)3](OTf)2 and 2,6-diisopropylaniline. Complex 1 underwent substitution with phosphines or phosphites, indicating the labile character of the η6-aniline ligand. Complex 1 mediated cycloaddition reactions of several alkynes in refluxing ethanol: the [2 + 2] dimerization for Ph{single bond}C{triple bond, long}C{single bond}Ph and the [2 + 2 + 1] trimerization for Ph{single bond}C{triple bond, long}C{single bond}H and CH3C6H4{single bond}C{triple bond, long}C{single bond}H. The unexpected cyclobutadiene complex [Cp*Rh(η4-C4(C(O)CH3)2H(SiMe3))] was obtained from complex 1 and Me3Si{single bond}C{triple bond, long}C{single bond}C{triple bond, long}C{single bond}SiMe3 and structurally characterized by X-ray diffraction.
