    Giffordene (=(2Z,4Z,6E,8Z)-2,4,6,8-undecatetraene; 9f) and five steroisomers are new C11H16 hydrocarbons from the marine brown alga Giffordia mitchellae. Their synthesis is based on non-stereoselective Wittig reactions of (E)-2-alkenals with appropriate acetylenic phosphoranes and subsequent chromatographic separation of the resulting (E/Z)-pairs. The uniform enynes (>98% purity) are then stereospecifically

  • Regio- and Stereoselective Synthesis of Vinylallenes by 1,5-(SN′′)-Substitution of Enyne Acetates and Oxiranes with Organocuprates

    substitution patterns react with organocuprates regioselectively under 1,5-(SN2′′)-substitution to provide vinylallenes 11 and 12. With lithium dimethylcuprate, reduced vinylallenes originating from a (formal) transfer of a hydride ion to the substrate are formed in some cases. The products are usually obtained as mixtures of (E/Z)isomers; however, pure (E)-vinylallenes are formed occasionally. The 1,5-substitutions

  • The elimination of carbon monoxide from molecular ions of phenol and other [C6H6O]+˙ isomers
    作者:H. J. Walther、H. Eyer、U. P. Schlunegger、C. J. Porter、E. A. Larka、J. H. Beynon
    DOI:10.1002/oms.1210170206
    日期:1982.2
    AbstractPhenol and five acyclic isomeric compounds have been investigated using electron impact and field ionization techniques, mass analysed ion kinetic energy spectrometry and collision induced dissociation mass analysed ion kinetic energy spectrometry. The kinetic energy release data corresponding to the elimination of carbon monoxide from the molecular ions show that at least two structures of the reactant ion are involved. The electron impact and field ionization collision induced dissociation mass analysed ion kinetic energy spectra indicate that under electron impact conditions, the phenol ion partially isomerizes to another ion structure. An isomerization of about 40% to the structure of cis‐2‐hexen‐4‐yn‐1‐al is in good accordance with the spectral data.
  • Structure of gas phase [C5H6]+˙ ions
    作者:Robert Flammang、Philippe Meyrant、André Maquestiau、Eric E. Kingston、John H. Beynon
    DOI:10.1002/oms.1210200316
    日期:1985.3
    AbstractCharge‐stripping spectra have been used to differentiate ionized cyclopentadiene from its acyclic isomers. The minimum amounts of translational energy lost during the charge‐stripping processes and the relative charge‐stripping efficiencies, which are also structurally important parameters, have been measured for these ionic species. [C5H6]+˙ ions, formed by dissociative ionization of various precursors in the ion source are found, usually, to be a mixture of cyclic and acyclic ions. In contrast, [C5H6]+˙ ions, derived from the dissociation of metastable molecular ions from a series of organic compounds, have the cyclopentadienyl structure. This structure was confirmed by collision‐induced dissociation of ions formed in the first field‐free region of a triple sector mass spectrometer.
