Beschreibung

General description

Copper(II) 2-ethylhexanoate is a crystalline solid that dissolves easily in nonpolar solvents. It exhibits moderate thermal stability and is often used as a catalyst or precursor in chemical vapor deposition and sol-gel processes. Its coordination structure allows it to form stable complexes, making it suitable for high-performance material applications.

Application

Copper(II) 2-ethylhexanoate is used as

• A precursor in the trifluoroacetate metal-organic deposition process for fabricating YBa_₂Cu_₃O_₇₋y (YBCO) coated conductors, contributing to high critical current density and improved film quality.
• A metal-organic precursor in photo deposition processes to synthesize metastable Ag–Cu alloy thin films under ambient conditions, for catalyzing the CO₂reduction reaction.
• A copper catalyst in asymmetric aminative ring-opening reactions of tetrasubstituted donor–acceptor cyclopropanes, enabling the high yield and high enantioselective synthesis of α-tertiary amines.
