Hajos–Parrish–Eder–Sauer–Wiechert Reaction - Reaction Mechanism
... stoichiometric amount of labeled water (H218O) supported a carbinolamine mechanism.Therefore, Hajos put forward (1974) a hemiaminal intermediate ... involved in hydrogen bonding The hemiaminal (carbinolamine) put forward by Hajos in 1974 can change to a tautomeric iminium hydroxide intermediate.The iminium hydroxide ion caused enolization of the side chain ... The Hajos 1974 carbinolamine mechanism has had an unwitting support in a more recent paper by Michael Limbach ...
