Quizplus · Accepted Answer

Only esters with two or three hydrogen atoms on the α-carbon (the carbon adjacent to the carbonyl carbon) can undergo Claisen reactions. This is because the reaction involves deprotonating the α-carbon, and if there are no hydrogen atoms present, the reaction cannot occur. Esters with more than three hydrogen atoms on the α-carbon can undergo aldol condensation reactions instead.
