Abstract

Dilithiated carboxylic acids are versatile intermediates in organic synthesis'. Not only are these compounds easily prepared from carboxylic acids and two equivalents of lithium diisopropylamide (LDA) in THF-hexane solution, but their nucleophilic character makes them susceptible to react with a large number of electrophilic reagents. The structure 1 was proposed by Creger' in accordance with the HSAB principle3. Di- ... A recent study about the structure of lithium derivative of ...
