 The carbonyl is then reformed and a double bond in the benzene ring attacks the carbon atom in the pronated imine cation.Water then acts as a base and deprotonates the α-carbon, reforming the aromatic ring and pushing electrons onto oxygen.The oxygen, which now has a negative formal charge, then attacks a hydrogen on the hydronium, resulting in an α-aminobenzylphenol, with water as the only byproduct.
