Exo-functionalized shape-persistent [2+3] cage compounds: Influence of molecular rigidity on formation and permanent porosity

Exo-functionalized [2+3] cage compounds were synthesized by using two different bissalicylaldehydes as molecular precursors in the reaction with triptycene triamine to study the influence of the rigidity of the molecular structure of [2+3] cages on their

Selective Preparation of Polycyclic Aromatic Hydrocarbons. Part 7. A Preparative Route to 10,11-Dihydro-5H-dibenzo-cycloheptenes Using Friedel-Crafts Intramolecular Cyclobenzylation

Cyclobenzylation of 2-hydroxymethyldiphenylethanes 4 and 2,2'-bis(hydroxymethyl)diphenylethanes 13 in the presence of a solid perfluorinated sulfonic acid resin, Nafion-H, as a catalyst results in novel polycyclic aromatic hydrocarbons, dibenzocyclopentenes.Dibenzocyclopentenes were also prepared from diphenylethanes by a benzylation reaction, which incorporates chloromethylation of a hydrocarbon followed by Friedel-Crafts intramolecular cyclization reaction.The present method involving the action of ClCH2OMe and TiCl4 on a variety of diphenylethanes (constructed such that electrophilic substitution occurs ortho to the diphenylethane linkage) offers a convenient, mild one-pot synthesis of substituted dibenzocycloheptenes.The mechanism of these reactions is also discussed.
