In summary, the dinuclear vanadium(V) dihemisalen complexes
on the hexaarylbenzene scaffold were designed and synthesized,
where the characteristic behaviors were found in the complexation
of the dihemisalen ligand with VO(OiPr)3. Furthermore, the
desymmetrized vanadium(V) complex 1ccis was formed from the
key intermediate 3cis. These complexes are considered to be of
potential to promote various reactions including the pinacol cou-
pling through dual activation by metals. Further investigation on
the application of the dinuclear hemisalen complexes for catalysis
is now in progress.
