Inversion of configuration at the tetrahedral carbon centres of dipola
r spiro-sigma-complexes formed by coupling 2-(N-benzylamino)tropone, 2
-(N-benzylamino)thiotropone or N,N'-dibenzyl-2-aminotroponimine with e
lectrophilic aromatic and heterocyclic compounds has been found to occ
ur intramolecularly with energy barriers accessible to measurement by
means of dynamic H-1 NMR spectral techniques.
