A mechanism for the acid catalyzed α-substitution reaction in which
Concept introduction:
In the presence of aqueous acids ketones tautomerize to their enol forms. The nucleophilic displacement of the chloride ion of selenyl chloride by the attack of the double bond of the enol and the subsequent deprotonation yields the product required.
To propose:
A mechanism for the acid catalyzed α-substitution reaction in which ketones react slowly with benzeneselenyl chloride in the presence of HCl to yield α-phenylselenoketones.
