Abstract:
The first metal-mediated efficient synthesis of octasubstituted semibullvalenes, including octaalkyl and mixed tetraalkyl and tetraphenyl derivatives, was developed. The structures of these semibullvalenes were determined by single-crystal X-ray structural analysis. Their intramolecular skeletal rearrangement and reaction chemistry were investigated.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
