Used primarily as a catalyst in organic synthesis, particularly in cross-coupling reactions, enabling the formation of carbon-carbon and carbon-heteroatom bonds. It is also employed in the preparation of nickel-based complexes for various research applications. In material science, it serves as a precursor for the synthesis of nickel-containing nanomaterials and thin films. Additionally, it finds use in electrochemical studies and as a reagent in fluorination processes due to the presence of trifluoroacetate groups.
