  Photoreduction of Diaryl Disulfides by Quadruply Bonded Dimolybdenum and Ditungsten Complexes

  摘要：

  The quadruple metal-metal bonded complexes, M(2)Cl(4)(dppm)(2) (M = Mo, W; dppm = bis(diphenylphosphino)methane), photoreact with disulfides in nonaqueous solvents to yield M(2)(III) addition products. Excitation (lambda(exc) > 435 nm) of the dimolybdenum photoreagent in the presence of PhSSPh affords Mo2Cl5(dppm)(2)(SPh). Whereas the MO(2)(III) edge-sharing bioctahedron is only accessible by photochemistry, W2Cl4(dppm)(2) is thermally and photochemically oxidized by PhSSPh to W2Cl4(dppm)(2)(SPh)(2), but reaction to the W-2(III) edge-sharing bioctahedron is greatly accelerated by light. The photolysis quantum yield for the Mo2Cl4(dppm)(2) photochemistry increases for excitation wavelengths to the blue of 436 nm (phi(p)(436) = 0.01 phi(p)(405) = 0.11, phi(p)(360) = 0.23) and asymptotically p p approaches a maximum at wavelengths less than 320 nm phi(p)(313) = 0.27). The action spectrum red shifts by similar to 50 p nm when the photoreagent is W2Cl4(dppm)(2). The wavelength dependence of M(2)Cl(4)(dppm)(2) photochemistry and the presence of long-lived intermediates in the transient absorption spectra of M(2)X(4)(PP)(2) complexes (M = Mo and PP = dmpm = bis(dimethylphosphino)methane; M = W and PP = dppm) suggest that reactivity is derived from metal-localized excited states lying to higher energy of the delta delta* excited state.

  The complex [Mo2(C≡CSiMe3)3(μ,η2:η2-HC≡CSiMe3)μ,η1-CC(SiMe3)-η2-C⋮CSiMe3}(μ-dmpm)2][Li(dme)] ([1][Li(dme)]; dmpm = 1,2-bis(dimethylphosphino)methane, dme = 1,2-dimethoxyethane) was prepared in 32% yield from the reaction between Mo2Cl4(dmpm)2, LiCCSiMe3, and HCCSiMe3 in dme. A single-crystal X-ray diffraction study of [1][Li(dme)0.5(OEt2)0.5] revealed that 1 contains an alkynylvinylidene ligand derived
