Stepwise synthesis and reactivity of Ph2PCH2PPh2-stabilized mixed-metal clusters containing three or four different metals

The reactions of the carbonylmetalate anions [m]- = [Co(CO)4]-, [Fe(CO)3NO]-, [Mn(CO)5]-, [Mo(CO)3Cp]-, and [W(CO)3Cp]- with the trinuclear clusters [PdMCoX(CO)3(dppm)2] (M = Pd, Pt; X = Cl, I; dppm = μ-Ph2PCH2PPh2), [Pd2FeI(CO)2NO-(dppm)2], [Pd2MnCl(CO)4(dppm)2], [PdMMoCpCl(CO)2(dppm)2], and [PdMWCpCl(CO)2(dppm)2] occur by substitution of the Pd-bound halide by the carbonylmetalate anions. As a result of Pd-m bond formation, they afford [Pd2Co2(CO)7(dppm)2] (3a), [Pd2Mn2(CO)9(dppm)2] (10), and new tetranuclear clusters [PdMCoFe(CO)6(NO)(dppm)2] (M = Pd, 4a; M = Pt, 4b), [PdMCoMn(CO)8(dppm)2] (M = Pd, 5a; M = Pt, 5b), [PdPtCoMoCp(CO)6(dppm)2] (6b), [Pd2FeCo(CO)6(NO)(dppm)2] (8), [PdMMoCoCp(CO)6(dppm)2] (M = Pd, 13a; M = Pt, 13b), and [Pd2WCoCp(CO)6(dppm)2] (14). These clusters possess a metalloligated triangular framework PdMM′m, with three (M = Pd) or four (M = Pt) different metals, the Pd, M, and M′ atoms constituting the triangle and m belonging to the metalloligand. The stepwise syntheses used in this work have led to the isolation of two pairs of positional isomers: [PdPtCoMoCp(CO)6(dppm)2] (6b), [PdPtMoCoCp(CO)6(dppm)2] (13b) and [Pd2CoFe-(CO)6(NO)(dppm)2] (4a), [Pd2FeCo(CO)6(NO)(dppm)2] (8), respectively, which do not interconvert and present interesting spectroscopic (1R, NMR) features. The substitution of the halide of [PdMCoX(CO)3(dppm)2] was shown to depend on the nature of (i) the halide (Cl vs I), (ii) the incoming carbonylmetalate anion [m]-, and (iii) the solvent used for the reaction. The lability of the exocyclic Pd-m bond has been studied with respect to the nature of both the endocyclic metals (Pd, M, and M′) and the exocyclic metal m. These studies reveal that (i) the space available for coordination at the Pd center decreases in the order [M′] = Co(CO)3 ? Mo(CO)2Cp, (ii) the Pd-m bond is less labile when M = Pd than when M = Pt, and (iii) the steric hindrance of the metalloligand increases in the sequence of m = Co(CO)4 ≤ Fe(CO)3NO ? Mn(CO)5 ? Mo(CO)3Cp ≈ W(CO)3Cp.
