| Outline of Final Research Achievements |
The reductive coupling reactions of carbonyl compounds provide an important method for the construction of a vicinally functionalized carbon-framework. However, the intermolecular cross-pinacol coupling reaction is still a challenging issue due to the difficulty in the discrimination of two aldehydes in the reaction. In this context, we envisioned that the controlled arrangement of two metals on the rigid scaffold can provide spatially regulated reaction sites for the cross-pinacol coupling reaction. As a result, intermolecular cross-pinacol coupling reaction between aliphatic and aromatic aldehydes using hetero dinuclear dihemisalen complexes with vanadium(V) and titanium(IV) on the hexaaryl benzene scaffold was achieved.
