Product formed when a 1,6-diester instead of a 1,7-diester is used has to be given. Concept Introduction: Claisen Condensation is the reaction of an ester having an α − hydrogen with one equivalent of a base to yield a β − keto ester. Mechanism for Claisen Condensation: A base abstracts a proton from the α − c a r b o n forms enolate ion. The enolate ion gets attached to the carbonyl carbon of another ester. The negative charge on oxygen of the carbonyl group reforms, by removing an alkoxide ion.
