摘要：

The reactions of 3,5,7-trimethyltropolone and 2-(N-benzylamino)tropone with 6-bromo-5,7-dinitrobenzo[e]-1,2,3,4-tetrazine 1,3-di-N-oxide afforded novel bipolar spiro σ-complexes. The kinetic and activation parameters of the R,S-enantiotopomerization of a chiral spiro σ-complex of 2-(N-benzylamino)tropone were determined using dynamic 1H NMR spectroscopy.
