Synthesis of Nitroolefins and Nitroarenes under Mild Conditions

摘要

1,3-Disulfonic acid imidazolium nitrate {[Dsim]NO_(3)} was prepared and characterized as a new ionic liquid and nitrating agent for the ipso-nitration of various arylboronic acids and nitro-Hunsdiecker reaction of different α,β-unsaturated acids and benzoic acid derivatives, by in situ generation of NO_(2) to give various nitroarenes and nitroolefins without using any cocatalysts and solvents under mild conditions.
