Abstract Solutions of Fe III salts and β-keto esters have been investigated by means of electrospray ionization mass spectrometry. The complexes formed in such solutions have been considered previously as active intermediates in Fe III-catalyzed Michael additions. By using different Fe III salts with a set of β-keto esters, cation and anion mass spectra were analyzed and the effects of ester concentration, the role of the counterion, and the ...
