  Synthesis, Reactions, and Structural and NMR Features of [2.2]Metacyclophane Monoenes and Their Tricarbonylchromium and Cyclopentadienyliron(+) Complexes

  摘要：

  8,16-Dimethyl-, 5,8,13,16-tetramethyl, and 4,6,8,12,14,16-hexamethyl[2,2]metacyclophanene have been synthesized from the corresponding methyl-substituted 3-thia[3.2]metacyclophane precursors via a Wittig rearrangement-Hofmann elimination procedure. Simple addition of bromine or similar electrophiles to the bridge double bond of the cyclophane monoenes did not occur; rather, the methyl-substituted dihydropyrenes were formed. However, mono- and bis-tricarbonylchromium and monocyclopentadienyliron complexes were obtained using ligand-exchange reactions. Addition of bromine to the cyclophane bridge double bond of the iron complex did occur, but unusually slowly. Surprisingly, debromination rather than dehydrobromination occurred when the dibromo addition product was treated with a variety of bases. Photoisomerization of the monoenes and nucleophilic substitution of the metal complexes was also investigated. The geometries of the monoenes and their complexes were compared to the cyclophanes and the cyclophanedienes and to the monothia- and dithiacyclophanes, by comparison of X-ray and calculated structural data and NMR spectroscopic data. Introduction of double bonds into the cyclophane bridges causes the cyclophane step to be less steep but increases distortion of the internal atoms out of the plane of the benzene rings. Making the bridges nonidentical also causes a sideways twist of the step.
