Description

Iodonium, [4-(Trifluoromethyl)Phenyl](2,4,6-Trimethylphenyl)-, Tetrafluoroborate(1-) (1:1) is a specialized iodonium salt, a key class of photoacid generators (PAGs) and versatile arylating agents. This compound is valued for its unique reactivity and stability, enabling precise control in advanced chemical synthesis and materials engineering. It is primarily sought by R&D chemists and process engineers in the pharmaceutical, agrochemical, and advanced electronics industries for applications requiring efficient cationic initiation or selective aryl group transfer.

Application

• Photoacid Generator (PAG) in Advanced Photoresists: A critical component in chemically amplified resists (CARs) for deep-UV (DUV) and extreme-UV (EUV) lithography in semiconductor manufacturing.
• Cationic Photoinitiator for Polymerization: Used to initiate the ring-opening polymerization of epoxides, vinyl ethers, and other monomers in UV-curable coatings, inks, and adhesives.
• Arylating Agent in Organic Synthesis: Facilitates the introduction of the 4-(trifluoromethyl)phenyl group into target molecules under mild conditions, useful in medicinal chemistry and material science.
• Catalyst and Reagent in Cross-Coupling Reactions: Employed as an electrophilic aryl source in metal-catalyzed or metal-free coupling reactions to construct complex biaryl structures.
• Research & Development: Serves as a valuable building block and reagent for developing new synthetic methodologies and functional materials in academic and industrial labs.
