Purpose:

Organic synthesis and coordination chemistry
Metal chelating agent
Synthesis of transition metal complexes
The β -dione structure (enol form) can form stable chelates with lanthanide elements (such as Eu³⁺, Tb³⁺) and transition metals (Cu²⁺, Pd²⁺), and is used for:

Fluorescent materials: Rare earth complexes may be used as luminescent materials (OLED, biomarker probes).

Catalyst: Such as catalyzing C-C coupling reactions or oxidation reactions.

(2) Fluorine-containing blocks
Introduction of trifluoromethyl:
As a fluorine-containing synthon, trifluoromethyl is introduced into the target molecule through hydrolysis or reduction reactions for fluorination modification of drugs or pesticides.

2. Materials Science
Precursor of luminescent materials
Complexes formed with rare earth ions may have high luminous efficiency and be used in anti-counterfeiting inks or display technologies.

Polymer modification
As a crosslinking agent or functional monomer, it improves the heat resistance and hydrophobicity of polymers (by using trifluoromethyl).

3. Intermediates for pharmaceuticals and pesticides
Development of fluorine-containing drugs
Trifluoromethyl can enhance the metabolic stability and lipid solubility of drugs and is potentially used in:

Anti-inflammatory/anti-tumor drugs: β -dione derivatives with similar structures have biological activity.

Antibacterial agent: Fluorine-containing groups may enhance membrane permeability.

Pesticide synthesis
As a precursor of fluorine-containing heterocyclic compounds (such as triazoles).

4. Analytical Chemistry
Spectral analysis reagents:
It selectively combines with metal ions and is used for ultraviolet/fluorescence detection (such as trace metal analysis).
