- Nonconjugated , -unsaturated ketones, such as 3-cyclohexenone, are in an acid-catalyzed equilibrium with their conjugated , -unsaturated isomers. Propose a mechanism for this isomerization.Aldehydes and ketones react with thiols to yield thioacetals just as they react with alcohols to yield acetals. Predict the product of the following reaction, and propose a mechanism:Provide a mechanism for the following transformation: CrO3 но, H30*
- Provide the product and mechanism for the reaction: ОН Cro, H,SO, H,0provide a mechanism which explains the following conversion OH ist NaOH H₂ON Ph :0: CH3 Primary amines add to aldehydes and ketones to give imines. Imines are formed in a reversible, acid-catalyzed process that begins with nucleophilic addition of the primary amine to the carbonyl group, followed by transfer of the proton to yield a neutral carbinolamine. Protonation of the hydroxyl group converts it into a good leaving group and an E1-like loss of water yields an iminium ion. Deprotonation yields the product imine and regenerates the acid catalyst. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions CH3 NH₂OH NH₂OH Ph- :0: OH CH3 CH3 36
- When diethyl ether (CH3CH2OCH2CH3) is treated with concentrated HBr, the initial products are CH3CH2Br and CH3CH2OH. Propose a mechanism to account for this reaction.Propose a mechanism for the following transformation: to OH (H,SO4] MEOH MeoAmantadine is effective in preventing infections caused by the influenza A virus and in treating established illnesses. It is thought to block a late stage in the assembly of the virus. Amantadine is synthesized by treating 1-bromoadamantane with acetonitrile in sulfuric acid to give N-adamantylacetamide, which is then converted to amantadine.
