The Malonic Acid synthesis is similar to the Acetoacetic Ester synthesis It uses diethyl malonate as the main starting material Draw the structure of diethyl malonate (malonic ester) Diethyl malonate can be hydrolyzed back to malonic acid and if heat is applied after the hydrolysis, will decarboxylate. Draw the mechanism for this transformation starting with malonic acid. Indicate the new C-C bonds in each molecule and then provide the organohalides which were used to synthesize each compound using the malonic...
