Reactions of Cp*GaCl2 and Cp*2GaCl (Cp*=η1-C5Me5), respectively, with different carbonylmetalate anions are compared to yield the transition-metal–gallium complexes [(η5-Cp*Ga)W(CO)5] (1), [Fe2(CO)62] (2), [Ga3] (3), [Cp*2Ga] (4), [Co2(CO)62Co(CO)3] (5) and [2(μ-CO)] (6). The results show that both starting materials offer an alternative synthetic route to subvalent Cp*Ga(I) compounds via reductive dehalogenation reactions in comparison to the previously used reactions starting from Cp*Ga itself. Starting from Cp*2GaCl, Cp* elimination reactions are observed additionally, a process which dominates much more in the case of Cp*InCl2 as a starting material. In these reactions with [CpFe(CO)2]− and [CpW(CO)3]−, [In3] (7) and [In3] (8), respectively, are obtained in good yield.
