Abstract
The commonly accepted mechanism for the acid-catalyzed disproportionation of 1, 2- dihydroquinolines involves a hydride transfer from C-2 of one dihydroquinoline molecule to C-4 of another molecule which has already been protonated at C-3. This mechanism is shown to be incorrect. The proposed intermediate is shown to react by solvent addition and not by reduction under the conditions of the reaction. Evidence has been obtained which ...
