Compounds [M(AuPMe3 )11 (AuCl)](3+) (M=Pt, Pd, Ni) (1-3), [Ni(AuPPh3 )(8-2n) (AuCl)3 (AlCp*)n ] (n=1, 2) (4, 5), and [Mo(AuPMe3 )8 (GaCl2 )3 (GaCl)](+) (6) were selectively obtained by the transmetalation of [M(M'Cp*)n ] (M=Mo, E=Ga, n=6; M=Pt, Pd, Ni, M'=Ga, Al, n=4) with [ClAuPR3 ] (R=Me, Ph) and characterized by single-crystal X-ray diffraction and ESI mass spectrometry. DFT calculations were used to analyze the bonding situation.

- The study explores the reactions of various cationic transition metal acetonitrile complexes with GaCp*, focusing on complexes of Fe, Co, Cu, and Ag.
- The reaction of [Fe(CH3CN)6][BArF]2 with GaCp* results in a redox-neutral Cp* transfer to form [Cp*Fe(GaCp*)3][BAr(F)], while Co undergoes oxidation to Co(III) when reacting with GaCp*.
- The synthesis of new homoleptic and dimeric compounds involving Cu and Ag is reported, all characterized using NMR spectroscopy, X-ray diffraction, and elemental analysis.
