Reactions of the rhenium dicarbonyl complexes Re2X4(dppm)2(CO)2 (X = Cl, Br) and the mixed carbonyl-isocyanide complexes Re2Cl4(dppm)2(CO)(CNR) (R = tert-Bu, xylyl) with trimethylphosphine and trialkyl phosphite ligands. Structural characterization of the complexes [Re2Cl3(.mu.-dppm)2(CO)2L]PF6 (L = PMe3, P(OEt)3) that contain an unsymmetrical carbonyl bridge

Redox reactions between metal–metal multiple bonds and carbon disulfide

Autor: Ju-Sheng Qi, Phillip E. Fanwick, Richard A. Walton, Paul W. Schrier

Publikováno v: J. Chem. Soc., Chem. Commun.. :1737-1739

Carbon disulfide is reduced by triply bonded complexes of the type [Re2X4(µ-LL)2][X = Cl or Br; LL = Ph2PCH2PPh2(dppm) or Ph2AsCH2AsPh2(dpam)] to afford the edge-shared bioctahedral dirhenium(III) species [Re2(µ-S)(µ-X)X3(CS)(µ-LL)2], which can i

Reactivity of quadruply bonded dimolybdenum(II) complexes with alkyl isocyanides: Mo-Mo bond cleavage or retention?

Autor: Richard A. Walton, Ju-Sheng Qi, W. S. Harwood

Publikováno v: Polyhedron. 5:15-23

The 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,
