Steric and electronic effects in imine-hemiaminal ring-chain tautomerism

Derrick, Sean D.,Boehme, Richard,Wong, Ken M.,Nemeth, Frank,Tanaka, Kelly,Rumberg, Brian,Beekman, Richard A.,Dibble, Peter W.

, p. 7679 - 7690 (1996)

We have examined a series of 1,3-dihydro-1-isobenzofuranamines that exist in an imine/hemiaminal ring-chain tautomerism. 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.
