Title: Lanthanide complexes of 3-acetyl-4-hydroxy-6-methyl-2H-pyran-2-one

Abstract

The title ligand (H(Dh), dehydroacetic acid) reacts with lanthanide(III) acetates in anhydrous methanol to form complexes of formula (M(Dh){sub 3}(MeOH)). When hydrated lanthanide acetates are used, hydrated compounds such as (Ce(Dh){sub 3}(H{sub 2}O)) or (Eu(Dh){sub 3}(H{sub 2}O)).H{sub 2}O are obtained. The reaction of lanthanum triacetate with H(Dh) yields the mixed complex (La(Dh){sub 2}(O{sub 2}CMe)), formation of the 1:3 complex also being unfavored in the presence of a large ligand excess. The complexes have been characterized by infrared and NMR ({sup 1}H and {sup 13}C) spectroscopy and by thermogravimetric measurements.
