O EtOCOET H N Eto EtOH Reactions of a primary or secondary amine with diethyl carbonate under controlled conditions gives a carbamic ester. Write a detailed mechanism for this reaction (shown above) which proceeds in 4 steps, including proton transfer steps. Then draw Intermediate 3 in the window provided. The mechanism is detailed as follows: Step 1: Nucleophilic attack to yield zwitterion intermediate 1. Step 2: Protonation/deprotonation (i.e. "proton transfer") of zwitterion 1 to yield intermediate 2. Step 3: Intramolecular...

The acetoacetic ester synthesis is a carbonyl alkylation reaction. It is used to prepare methyl ketones from primary alkyl halides, lengthening the carbon chain by three atoms. Thus, the product can be visualized as being a "substituted acetone." The reaction consists of three steps: generation of the enolate anion followed by S2 reaction with a primary alkyl halide, ester hydrolysis under acid conditions, and decarboxylation. 1. NaOEt 2.
