Zugriff:
Benzylic-type carbanions react with nitroarenes under mild conditions in the presence of DBU and trialkylchlorosilanes to form tetra-and pentacyclic azaarenes. The reaction proceed via transformation of the σH-adduct formed from carbanion and nitroarene. Reaction proceed under mild conditions at room temperature and does not require transition-metal reagents at any stage of the process.
