Molecular iodine exhaustively iodinates aromatic hydrocarbons in the presence of potassium peroxodisulfate, concentrated sulfuric acid, and trifluoroacetic acid to give the periodinated aromatic compounds. Benzene and other moderately activated and deactivated arenes are readily converted into the corresponding periodinated derivatives in good to high yields.
N-substituted) pentaiodobenzenes using site-selective nucleophilic aromatic substitution (SNAr) reactions. Single-crystal X-ray diffraction analysis and theoretical calculations of thus synthesized pentaiodobenzenes reveal that their highest occupied molecular orbital (HOMOs) are composed of circularly delocalized σ-symmetric orbitals, as found in hexa-substituted benzenes bearing heavy atoms such as selenium
摘要:我们报道了利用位点选择性亲核芳香取代(SNAr)反应合成氧和氮取代(O 和 N 取代)五碘苯。由此合成的五碘苯的单晶 X 射线衍射分析和理论计算表明,其最高占据分子轨道 (HOMO) 由圆形离域 σ 对称轨道组成,如在带有硒和碘等重原子的六取代苯中发现的那样。

Synthesis and photophysical properties of tetra and pentaarylated fluorobenzenes
Suzuki–Miyaura cross-coupling reactions of novel 1,2- and 1,4-difluorotetraiodobenzene and of 1-fluoropentaiodobenzene. These Suzuki–Miyaura reactions allowed a convenient synthesis of fluoro-substituted aryl benzenes. The photophysicalproperties (absorption and fluorescence) of the products have been studied.
