- The mechanism for acidic hydrolysis of a nitrile resembles the basic hydrolysis, exceptthat the nitrile is first protonated, activating it toward attack by a weak nucleophile (water).Under acidic conditions, the proton transfer (tautomerism) involves protonation on nitrogen followed by deprotonation on oxygen. Propose a mechanism for the acid-catalyzedhydrolysis of benzonitrile to benzamide.arrow_forwardAmobarbital is a sedative marketed under the trade name Amytal. Propose a synthesis of amobarbital, using diethyl malonate and urea as two of the starting materials.arrow_forwardShow how to convert carboxylic acids to other functional groups, and devisemultistep syntheses using carboxylic acids as starting materials and intermediates.Explain how acid chlorides are used as activated derivatives of carboxylic acidsarrow_forward
- Show how Gabriel syntheses are used to prepare the following amines.(a) benzylaminearrow_forwardMethamphetamine is a long-lasting, potent stimulant sold as a street drug. The synthesis is quite simple and one step in the synthesis is shown below. Using your knowledge of the reactions of amines, provide all the reagents necessary to complete the reaction below. Provide the reagents for step 1 and step 2 ,arrow_forwardShow how acid derivatives hydrolyze to carboxylic acids under either acidic or basicconditions. Explain why some acid derivatives (amides, for example) require muchstronger conditions for hydrolysis than other derivatives.arrow_forward
- Phenacetin is an analgesic compound having molecular formula C10H13NO2. Once a common component in over-thecounter pain relievers such as APC (aspirin, phenacetin, caffeine), phenacetin is no longer used because of its liver toxicity. Deduce the structure of phenacetin from its 1H NMR and IR spectra.arrow_forwardPhenylacetone can form two different enols.(a) Show the structures of these enols.(b) Predict which enol will be present in the larger concentration at equilibrium.(c) Propose mechanisms for the formation of the two enols in acid and in basearrow_forwardShow how to synthesize the following amines from the indicated starting materials.(a) N-cyclopentylaniline from anilinearrow_forward
- Show how to synthesize the following amines from the indicated starting materials byreductive amination.(a) benzylmethylamine from benzaldehydearrow_forward(D)The best route to synthesise aromatic primary amines is by reduction of the corresponding nitro compounds. Draw the reaction scheme for the preparation of p-toluidine.arrow_forwardWhich of the following statements is correct? An aldehyde can react with a secondary amine through a nucleophilic addition-elimination mechanism to give an enamine product. A ketone can react with a secondary amine through a nucleophilic addition mechanism to give an imine product. An ketone can react with a primary amine through a nucleophilic addition-elimination mechanism to give an enamine product. An aldehyde can react with a primary amine through a nucleophilic addition mechanism to give an imine product.arrow_forward
