Abstract
A bridging carbon analog of the well-studied bis(pyridyl)iminoisoindoline (BPI) can be produced via a one step reaction between diiminoisoindoline and pyridine-2-acetonitrile. The resultant bis(pyridineylidene)isoindoline (BPYI) is structurally analogous to BPI and can readily form metal complexes. However, it exhibits a markedly different electronic structure with intense absorption bands in the visible region of the spectrum.
