Dianions (2), (5), and (10), can be derived from the corresponding benzofurancarboxylic acids using lithium diisopropylamide, and are useful intermediates for the homologation of the parent acids.

The dianionic species, lithium 2-lithiobenzofuran-3-carboxylate (5) and lithium 3-lithiobenzofuran-2-carboxylate (11b) can be readily generated from the parent acids by reaction with lithium diisopropylamide in tetrahydrofuran at low temperatures.While co
