How is Diborylidynevanadium (CAS: 12007-37-3) typically synthesized?

Diborylidynevanadium (CAS: 12007-37-3) is synthesized through the reaction of vanadium tetrachloride with phenylboronic acid in the presence of an appropriate base. The synthesis typically involves a one-pot reaction that yields diborylidynevanadium with good selectivity and moderate to high yield. This method allows for the preparation of the compound in a controlled manner.
