examined a series of 1,3-dihydro-1-isobenzofuranamines that exist in an imine/hemiaminal ring-chaintautomerism. The tautomeric free energies are rationalized in terms of electronic and steric effects. A series of compounds bearing substituents of varying bulk have free energies that correlate well with substituent A values.
