Designing Synthetic Schemes using Reactions with Carboxylic Acids and Acid Derivatives: Complete the synthesis below using only benzene, toluene, propanoic acid, carbon dioxide and copper cyanide as your sources of carbon atoms (all carbon atoms in the products must come from these reactants). You can use any other reagents that do not incorporate C atoms into the structure as needed. This is a convergent synthesis - you will use the different reactants to start different branches of the synthesis, and then later perform steps that bring the different branches together to eventually converge in a final step to create the final product. Note that while there is an emphasis on reactions involving acids and acid derivatives, you may need reactions from involving alkenes, alcohols, alkyl halides, and aromatic rings in order to complete this synthesis. Pay careful attention to the number of carbons and where the carbonyl group is located in the final product. O=C=0 HO. Cu CEN
