Step-by-step solution

A cross Claisen Condensation or mixed Claisen Condensation is a condensation reaction between two different esters. Like a cross aldol addition, a cross Claisen Condensation is a useful reaction only if it is carried out under conditions that foster the formation of primarily one product. Otherwise, the reaction will form a mixture of products that are difficult to separate. Primarily, one product will be formed from the cross Claisen Condensation if one of the esters has no α - hydrogen (and therefore cannot
