Soluble in water. Slightly soluble in alcohol.


Copper(II) tetrafluoroborate is used in copper plating and in the production of printed circuits. It serves as an intermediate for homometallic, trinuclear heteroscorpionate complexes applied in studies of electronic and magnetic properties. It is also employed in the promotion of Diels-Alder reactions and decomposition of diazo compounds. Further, it is used as a component of fluxing and plating, as a catalyst and as an active filler in resin bonded abrasives. It is used in flame-retardant production, metal treatment, grain refining agents, electrolytic generation of boron and in the preparation of glazing frits. In addition it functions as an oxidizing agent and reacts with siloxycyclopropanes to generate beta acylalkylcopper(II) species.


Hygroscopic. Incompatible with acids, bases, strong oxidizing agents and strong alkali.
