What reagent(s)would accomplish the following transformation?

Question

Quizplus · Accepted Answer

The addition of HBr in the presence of peroxides (such as H2O2 or diethyl ether) is known as the peroxide effect. This reaction leads to anti-Markovnikov addition of HBr to an alkene, where the hydrogen adds to the carbon with fewer alkyl substituents. In this case, the double bond in the starting material is between a tertiary carbon and a secondary carbon. The peroxide effect causes the hydrogen to add to the secondary carbon, forming a more stable tertiary carbocation intermediate. The bromide ion then attacks the carbocation to complete the addition reaction.
