Indium-mediated chemoselective deprotection and demonochlorination of 2,2,2-trichloroethyl esters
摘要:
On treatment with indium metal, the 2,2,2-trichloroethyl carboxylates smoothly undergo deprotection to carboxylic acids and reductive demonochlorination to 2,27dichloroethyl esters, sharply depending on their structures. (C) 2007 Elsevier Ltd. All rights reserved.
Let's get fluorophilic! Tagging the imidazolium ionic liquids catalytically active in redox esterification with large fluorous substituents enables their facile recovery from reaction mixtures and multiple reuse without loss of activity. It also enables their application as catalysts in fluorous biphase catalysis and supercritical CO2.
