Heteroatom Cycloaddition at the (BN) Bay Region of Dibenzoperylene.

Cycloaddition-dehydration involving a BNBN-butadiene analogue at the bay region of a dibenzoperylene and a non-enolizable aldehyde provides a novel strategy for incorporation of the oxadiazadiborinane (B N CO) ring into the scaffold of a polycyclic aromatic hydrocarbon resulting in highly emissive compounds.
