Draw the structures of the organic products in each reaction of the following two-step synthesis. (Hint: The nucleophilic amine attacks the electrophilic carbonyl carbon, and the resulting intermediate undergoes a proton shift and dehydration. Recall what is eliminated in a dehydration process. The second step is a reduction reaction; the reducing agent is NaBH3CN (or H2, metal catalyst). The aromatic ring is unaffected by these reagents. Look at the product of the first reaction and consider what can be easily...

Draw the structures of the two carbocation intermediates that might form during the reaction of the alkene (below) with HCI. • You do not have to consider stereochemistry. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. • If the two carbocations differ in stability, select the reaction arrow from the dropdown menu, and draw the less stable carb • If two carbocations are energetically equivalent, separate the two structures with...
In the box provided, draw the structures of the phosphorus ylid and carbonylcompound that can be reacted in a Wittig reaction to form the alkene shown below.I need the mechanism to get the answers.
2. Briefly explain why ethanol, and not hexane, was used as a solvent in this reaction? 3. Why it is necessary to filter the crude coupling product through a column of anhydrous MgSO4? 4. Briefly explain why aryl bromides and iodides, rather than aryl chlorides or fluorides, are typically used as substrates in Pd-catalyzed coupling reactions. 5. Propose a synthesis for the molecule A shown below, using benzene, phenyl boronic acid, tert-butyl bromide and any inorganic reagents needed. A retrosynthetic...
