  Synthesis and properties of [4,5]dihomotropone (bicyclo[5.1.1]Nona-2,5-dien-4-one)

  摘要：

  The potentially through-bond "dihomoaromatic" title compound has been elaborated by means of a tandem acyloin-ring expansion sequence and shown by spectroscopic means not to possess significant ground-state polarization.

  Is Through-Bond Dihydroaromaticity Attainable? Preparation of [4,5]Dihomotropone, Investigation of Its Ground-State Properties, and an Attempt to Generate the Dihomotropylium Cation

  摘要：

  Construction of the first dihomotropone (6) has been accomplished. The key elements of the synthesis were a regiocontrolled expansion of a [4.1.1] bicyclic cr-bromo ketone and introduction of the dienone double bonds by means of the Garbisch method. The spectral properties of 6 under neutral and strongly acidic conditions are described and interpreted in terms of a lack of dihomoaromatic character. The parent bicyclo[5.1.1]nonadienyl cation is unstable and experiences ready Wagner-Meerwein rearrangement to the bicyclo[4.2.1]nonadien-7-yl cation. These features appear well suited to the ultimate evaluation of through-bond interaction in tricyclic homologues of 6 that carry perpendicular pi arrays in the third ring.
