Abstract
The differences in redox behavior of the monofunctional
bis(imino)acenaphthene
(BIAN) and bifunctional tetrakis(imino)pyracene (TIP) ligands have
been explored by treatment of the latter with PI<sub>3</sub>, TeI<sub>4</sub>, or BI<sub>3</sub>. These reactions result in the formation
of products involving the transfer of three or four electrons. Accompanying
DFT calculations reveal that in each case the extent of electron transfer
from each p-block element into the TIP ligand is dependent upon the
element–TIP bonding interactions
