Abstract

The reaction between the half-sandwich cyclopentadienyl complexes [M(eta (5)-C5Me5)Cl-2(PEt3)] (M = Rh, Ir) and [cis-M ' (C6F5)(2)(thf)(2)] (M ' = Pt, Pd; thf = tetrahydrofuran) affords the corresponding chloride-bridged heterobinuclear Rh, Ir/ Pt, Pd complexes [(PEt3)(eta (5)-C5Me5)M(mu -Cl)(2)M '(C6F5)(2)] (1-4). In contrast, similar reactions with the chloro-bridged binuclear compounds [{(M(eta (5)-C5Me5)Cl(mu -Cl)}2] (M = Ph, Ir) lead instead to the unexpected mixed salt complexes {Cp*M(mu -Cl)(3)MCp*}(2)[{(C6F5)(2)M '(mu -Cl}(2)] (M = Rh, Ir; M ' = Pt, Pd) (5-8) as a result of chloride transfer. The structures of [(PEt3)(eta (5)-C5Me5)Rh(mu -Cl)(2)Pt(C6F5)(2) (1) and {Cp*Rh(mu -Cl)(3)RhCp*}(2)[{(C6F5)(2)Pd(mu -Cl)}(2)] (6) have been determined by X-ray diffraction analyses. The reactivity of the new chloride-bridged heterobinuclear compounds 1-4 towards the alkynylating agents [M " (C drop CR)](n) (M " = Cu, Ag) has also been investigated: a new type of tetranuclear product, [(PEt3)Cp* M(mu -1 kappaC(alpha):eta (2)-C drop CPh)(2)M " (2)(mu -4 kappaC(alpha):eta -C drop CPh)(2)Pt(C6F5)(2)] (M = Rh, Ir; M " = Cu, Ag) (9-12), was obtained, and fully characterized in the case of complex [(PEt3)Cp*Rh(mu -1 kappaC(alpha):eta (2)- C drop CPh)(2)Cu-2(mu -4 kappaC(alpha):eta (2)-C drop CPh)(2)Pt(C6F5)(2)] (9).
