- Bisphenol A is made on a large scale by a condensation of phenol with acetone. Suggest an appropriate catalyst, and propose a mechanism for this reaction.arrow_forwardPropose a mechanism for the reaction of bisphenol A with phosgene.arrow_forwardPredict the products formed when cyclohexanone reacts with the following reagents. h) sodium acetylide, then mild H3O+arrow_forward
- Isoamyl acetate (also known as isopentyl acetate) is an ester that is referred to as “banana flavor” due to its odor that resembles that of banana. It can be synthesized from isopentyl alcohol and acetic acid via nucleophilic acyl substitution mechanism. Propose a mechanism for the synthesis of isoamyl acetate from acetic acid and isoamyl alcohol.arrow_forwardThe reagent diisobutylaluminum hydride (DIBALH) reduces esters to aldehydes. When nitriles are treated with DIBALH followed by mild acid hydrolysis, the product is also an aldehyde. Propose a mechanism for this reduction.arrow_forwardChoose starting materials and propose a synthesis strategy to synthesize Diazepam from Alprazolam, or synthesize Alprazolam from Diazepam. No mechanism is required.arrow_forward
- Describe how the following compounds could be prepared from cyclohexanone using an enamine intermediate:arrow_forwardPropose a mechanism for the reaction of benzyl acetate with methylamine. Label theattacking nucleophile and the leaving group, and draw the transition state in which theleaving group leaves.arrow_forwardThe 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_forward
