Metal-template-controlled stabilization of β-functionalized isocyanides

Reaction of 2-azidoethyl isocyanide 1, 2-azidophenyl isocyanide 2, or 2-nitrophenyl isocyanide 3 with complexes [Mo(CO)3(dppe)(py)] [4] or [W(CO)3(dppe)(Ni-≡CCH3)] [5] yields the isocyanide complexes [Mo(CO)3(dp

Syntheses, characterization and facial-meridional isomerism of tungsten tricarbonyl diphosphine complexes

The complexes fac-[W(CO)3(η2-dppf)(η1-dppm)] 4f, fac-[W(CO)3(η2-dppm)(η1-dppf)] 5f, fac-[W(CO)3(η2-dppf)-(η1-dppe)] 6f, fac-[W(CO)3(η2-dppe)(η1-dppf)] 7f, fac-[W(CO)3(η2-dppm)(η1-dppe)] 8f and fac-[W(CO)3(η2-dPpe)-(η1-dppm)] 9f have been prepared by treating fac-[W(CO)3(η2-diphos)(NCMe)] 1-3 [diphos = 1,1′-bis(diphenylphosphino)ferrocene (dppf), dppm (Ph2PCH2PPh2) or dppe (Ph2PCH2CH2PPh2)] with the corresponding diphosphines. The initially afforded facial isomers are converted into the meridional forms (4m-9m) in a subsequent, slow rearrangement process through opening of the chelated diphosphine ligand. A five-co-ordinate, square-pyramidal intermediate is presumed. In contrast, acid-assisted facial-meridional isomerization of 4f and 6f is likely via a seven-co-ordinate hydrido species. The new compounds have been characterized by elemental analyses and IR, mass and NMR spectroscopy.
