It can only begin with the enol form. Also, it is not the case where the enol form doesn't already exists in the first place. Although the carbonyls exist predominantly in the keto form, some of them are in the enol form. These enols can take part in the reaction. Even if these enols were consumed, the equilibrium would shift towards forming more enols, gradually the keto form would also deplete. | |
