Abstract

Acetylacetone (Hacac) admitted as a gas to an ion source containing CoCl~2~ adsorbed on a field ionization/field desorption emitter produces the ion [Co(acac)Cl]^+^. Similar ions arising from interaction of adsorbed salt and a ligand admitted as a gas were found for CoCl~2~ and trifluoroacetyl acetone, and for FeCl~2~ and acetylacetone. The chelation process represents a new kind of reaction of chemisorbed species in field ionization mass spectrometry.
