Alkenes can be hydrated to form alcohols by (1) hydroboration followed by oxidation with alkaline hydrogen peroxide and (2) acid-catalyzed hydration. Compare the product formed from each alkene by sequence (1) with those formed from (2).
Q.) Propene
Alkenes can be hydrated to form alcohols by (1) hydroboration followed by oxidation with alkaline hydrogen peroxide and (2) acid-catalyzed hydration. Compare the product formed from each alkene by sequence (1) with those formed from (2).
Q.)Cyclopentene
Like other electrophiles, carbocations add to alkenes to form new carbocations, which can then undergo substitution or elimination reactions depending on the reaction conditions. With this in mind, consider the following reactions of nerol, a natural product isolated from lemon grass and other plant sources. Treatment of nerol with TsOH forms α-terpineol as the major product, whereas treatment of nerol with chlorosulfonic acid, HSO3Cl, forms a constitutional isomer, α-cyclogeraniol. Write stepwise mechanisms for both processes. Each mechanism involves the addition of an electrophile—a carbocation—to a double bond.
