Study of formation and fragmentation of ionic complexes of polydentate ligands with Al(III) and glycerol by fast atom bombardment mass spectrometry. Part 1: Polydentate ligands
Abstract:The complexation reactions of aluminum ions with polydentate ligands such as 12-crown-4,15-crown-5, 18-crown-6, 1 ,lo-dithia-18-crown-6, dicyclohexyl-18-crown-6, dibenzo-18-crown-6, and dibenzo-24-crown-8 and acyclic analogs mono-, di-, tri-, tetra-, penta-, and hexaethylene glycols were studied using FAB mass spectrometry. These cyclic ligands form (M + 117)+, (M + 157)+, (M + 231)+, and (M + 253)' ions with different aluminum-containing species. Collisionally activated dissociations of these adduct ions gav… Show more
