Shigeno, Masanori published the artcileDirect C-H carboxylation forming polyfunctionalized aromatic carboxylic acids by combined Bronsted bases, Related Products of nitriles-buliding-blocks, the main research area is polyfunctionalized methyl benzoate preparation; arene carbon dioxide carboxylation Bronsted base promoted.
CO2 fixation into electron-deficient aromatic C-H bonds proceeded with the combined Bronsted bases LiO-t-Bu and LiO-t-Am/CsF/18-crown-6 (t-Am = CEtMe2) under a CO2 atmosphere to afford a variety of polyfunctionalized aromatic carboxylic acid derivatives RCO2Me [R = 2,4,6-tri-BrC6H2, 2,3-di-ClC6H3, 2-O2NC6H4, etc.].
Organic Letters published new progress about Aromatic hydrocarbons Role: RCT (Reactant), SPN (Synthetic Preparation), RACT (Reactant or Reagent), PREP (Preparation). 91-15-6 belongs to class nitriles-buliding-blocks, name is Phthalonitrile, and the molecular formula is C8H4N2, Related Products of nitriles-buliding-blocks.
