A series of new mono- and disubstituted perimidines with electron-withdrawing substituents in the naphthalene fragment has been synthesized. Their prototropic annular tautomerism has been investigated by 1H NMR spectroscopy. ... Keywords: perimidine, PPA (polyphosphoric acid), annular prototropy, arenesulfonation, acylation. ... We reported previously on the extremely slow annular prototropic tautomerism of derivatives of 2-trifluoromethylperimidine ...
