General description
The tautomeric properties of 3-chloro-2,4-pentanedione were studied using gas electron diffraction (GED) and quantum chemical calculations.
Application
3-Chloro-2,4-pentanedione was used in the synthesis of tetrathiafulvenyl-acetylacetonate (TTFSacacH), precursor of novel redox-active ligands.

The reaction of tris(alkylthio)tetrathiafulvalene thiolates with 3-chloro-2,4-pentanedione affords tetrathiafulvalene (TTF) moieties substituted by the acetylacetone function (TTFSacacH), precursors of novel redox-active ligands: the acetylacetonate ions (TTFSacac). These TTFSacacHs have been characterized by X-ray diffraction analyses, and similar trends have been

A new series of N1-(flavon-6-yl)amidrazones were synthesized by reacting the hydrazonoyl chloride derived from 6-aminoflavone with the appropriate sec-cyclic amines. The antitumor activities of these compounds were evaluated on breast cancer (MCF-7) and leukemic (K562) cell lines. Among the compounds
