    Instead of reacting via the expected coarctate cyclization pathway, 2-nitrosobenzonitrile undergoes a tandem nitroso-ene/intramolecular cyclization to form benzocisoxazol-3(1H)-imines in very good yields under neutral conditions and at moderate temperatures. Treatment of three of the imines with HBF4 results in dimerization/condensation to furnish unusual, delocalized cationic systems.
