Abstract

Molecular orbital calculations reveal that the keto tautomer of HOCHCHNHNCH₂, unlike the enol, does not represent a minimum in the ground state proton transfer potential. Excitations to the first excited singlet or triplet state leads to a rapid and barrierless transfer to the keto which becomes strongly preferred. Similar conclusion apply to a larger system with a full aromatic ring appended.
