Benzo- and Naphtho-derivatives of Triptycene: Synthesis and Properties
スポンサーリンク
概要
- 論文の詳細を見る
Several benzo- and/or naphtho-derivatives of triptycene were prepared in a manner of addition reaction of dehydronaphthalene (XIII) or a new type of aryne, dehydroanthraquinone (XVI) generated from 3-aminoanthraquinone-2-carboxylic acid (XV), with a few acenes. The absorption bands in longer wavelength region of their UV spectra and the chemical shift of bridgehead protons in their NMR spectra led to a conclusion that the spectra of those annelated triptycenes are elucidated in terms of a superposition and a sum of magnetic effects of separated component chromophores, respectively, and thereby indicate a negligible existence of the across-space π-electron interactions, if any, among three aromatic nuclei.
