通过使用便宜且可用的Oxone / H 2 SO 4氧化系统对1-苯基-5-碘咪唑进行氧化环化,已经开发了一种新型的制备咪唑取代的环状碘鎓盐的方法。新的多环杂芳烃的结构已通过单晶X射线衍射法确认,揭示了环状碘鎓盐的特征结构特征。发现新产生的侧接咪唑的环状碘鎓化合物易于与元素硫进行杂环化反应,从而以良好的收率提供了苯并[5,1- b ]咪唑并噻唑。
A novel method for selective generation of aryl radicals from diaryliodonium salts and iodanylidene malonates with sodium 2,2,6,6‐tetramethylpiperidine‐1‐oxyl (TEMPONa) as a single‐electron transfer (SET) reducing reagent is described. In the presence of various alkenes, aryl radicals formed after SET‐reduction of hypervalent iodine compounds undergo alkene addition and the adduct radicals that are
The synthesis of N‐arylimidazoles substituted at the sterically encumbered 5‐position is a challenge for modern synthetic approaches. A new family of imidazolyl aryliodonium salts is reported, which serve as a stepping stone on the way to selective formation of N1‐aryl‐5‐iodoimidazoles. Iodine acts as a “universal” placeholder poised for replacement by aryl substituents. These new λ3‐iodanes are produced
