Treatment of the perhalogenated cymantrenes [C5X4Br]Mn(CO)3 (X = Cl, Br) with butyl lithium and Au(PPh3)Cl yields, depending on the reaction conditions, the bi-or trimetallic σ, π-bridged cyclo-pentadienyl complexes [C5X5-n(AuPPh3)n]Mn(CO)3 with n = 1 or 2. Similarly, the bimetallic complexes [C5Cl4(AgPPh3)]Mn(CO)3 and [C5Cl4(AuCNtBu)]Mn(CO)3 can be obtained. Addition of Ni[PBu3]2C2H4) to [C5Cl4(AuPBu3)]Mn(CO)3 generated in situ results in oxidative addition of one ring CCl bond to Ni0 to give [C5Cl3(AuPBu3)[Ni(PBu3) 2Cl]]Mn(CO)3, the first complex with three different metals attached to one cyclopentadienyl ring. When the lithium cymantrenyl thiolates [C5Cl3X(SLi)]Mn(CO)3 (X = Cl, Li or SLi) are treated with Au(PPh3)Cl, the gold thiolates [C5Cl3Y(SAuPPh3)IMn(CO)3 with Y = Cl, AuPPh3 or SAuPPh3 are formed. 1997 Elsevier Science Ltd.
