Acetylation-substituted N-ethylcarbazole at the 3-position was synthesized in 80% yield using ZnCl2 as catalyst, and its corresponding functionalized bis-β-diketone compounds 2a and 2b were prepared by Claisen condensation with acceptable yields. Lanthanide complexes with the two compounds could be used as potential luminescent materials.
