  quadruply-bonded dimolybdenum(II) complexes Mo2(μ-dppm)2X4 (X = Br or I) can be prepared in high yield from Mo2(μ-dppm)2Cl4 (dppm = Ph2PCH2PPh2) via simple halide-exchange reactions (using NaX in acetone). The complexes Mo2(μ-dppm)2X4 (X = Cl, Br or I) react with one equivalent of RNC (R = i-Pr or t-Bu) in the presence of TlPF6 (in THF) or KPF6 (in acetone) to give [Mo2X3(dppm)2(CNR)]PF6, the first examples

  Reaction of Mo(2)Cl(4)(dppm)(2) (dppm = bis(diphenylphosphino)methane) with 6 equiv of [n-Bu(4)N][CN] or [Et(4)N][CN] in dichloromethane yields [n-Bu(4)N](2)[Mo(2)(CN)(6)(dppm)(2)] (1) and [Et(4)N](2)[Mo(2)(CN)(6)(dppm)(2)] (2), respectively. The corresponding one- and two-electron oxidation products [n-Bu(4)N][Mo(2)(CN)(6)(dppm)(2)] (3) and Mo(2)(CN)(6)(dppm)(2) (4)were prepared by reactions of 1

• Photoreduction of Diaryl Disulfides by Quadruply Bonded Dimolybdenum and Ditungsten Complexes

  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.
