摘要

New methods for the regioselective formation of radical anions are described. Dicarboxylates are generated by electrospray ionization mass spectrometry and lose carbon dioxide and an electron upon collision-induced dissociation to afford distonic ions. These radical anions also can be synthesized via laser desorption, chemical ionization, and electron ionization of dibenzyl esters. Subsequent fragmentation of the remaining CO2 ...
