Popis

General description

Triacetylmethane on condensation with 2,6-diisopropylaniline in toluene in the presence of p-toluenesulfonic acid yields 3-[1-(2,6-diisopropylphenylamino)ethylidene]pentane-2,4-dione.

Application

Triacetylmethane was used in the synthesis of novel metal complexes bis(3-acetyl-2,4-pentanedionato-O₂,O₃)palladium(II) and bis(3-acetyl-2,4-pentanedionato-O₂,O₃)magnesium(II).
