The compound is used in
Diels Alder reactions, for cyclopropanation of alkenes with diazo reagents, and as a Lewis Acid in Meinwald Rearrangement reactions on Epoxides.[4] In the former two applications, the copper(II) is reduced to a copper(I) catalyst.[3][5] The compound is also used for copper electroplating in fluoroborate-based plating baths.[6]
