- The key step in a reported laboratory synthesis of sativene, a hydrocarbon isolated from the mold Helminthosporium sativum, involves the following base treatment of a keto tosylate. What kind of reaction is occurring? How would you complete the synthesis?arrow_forwardNonconjugated , -unsaturated ketones, such as 3-cyclohexenone, are in an acid-catalyzed equilibrium with their conjugated , -unsaturated isomers. Propose a mechanism for this isomerization.arrow_forwardCan you draw the mechanism for the synthesis of cyclohexene from cyclohexanol through an acid-catalyzed dehydration reaction. Where Phosphoric acid donates a proton ((H^+)) to the hydroxyl group of cyclohexanol, forming a protonated cyclohexanol intermediate. • The protonated cyclohexanol undergoes dehydration, leading to the removal of a water molecule and the formation of cyclohexene. • The released proton combines with water to form hydronium ion (H3O+), regenerating the catalyst. The mechanism should illustrate the acid-catalyzed dehydration process, where phosphoric acid facilitates the removal of water from cyclohexanol, resulting in the formation of cyclohexene.arrow_forward
