Applications

Copper(II) acetate can act as an oxidant for carbanions, free radicals, and hydrocarbon compounds, enabling oxidative coupling reactions of electronegative substrates and solvent cleavage reactions of Si-C, Bi-C, Pb-C, and Sb-C bonds. It can also be used for the cyclopropanation of olefins with diazo esters or as a Lewis acid. Copper(II) acetate has oxidative activity toward carbanions. In the presence of pyridine, terminal alkynes can undergo oxidative coupling reactions to form diyne compounds.
