Final answer:
A) Hg(OAc)₂, ROH, NaBH₄. The correct reagents for alkoxymercuration-demercuration to prepare a given compound are Hg(OAc)2, ROH, and NaBH4, which correspond to answer A.
Step-by-step explanation:
To prepare a given compound using alkoxymercuration-demercuration, the correct set of reagents is:
Choosing from the provided options, the correct answer isThis method involves the addition of an alcohol (ROH) to an alkene in the presence of mercuric acetate (Hg(OAc)₂) followed by a reduction step using sodium borohydride (NaBH₄).
This process avoids direct hydration of the alkene and allows for the preparation of ethers with anti-Markovnikov selectivity.
Alkoxymercuration-demercuration is a synthetic method used to convert an alkene into an alcohol. In this reaction, Hg(OAc)₂ (mercury(II)acetate) and ROH (an alcohol) are added to the alkene, and the resulting mixture is treated with NaBH₄ (sodium borohydride).
This process follows the general mechanism of alkoxymercuration-demercuration, which involves the addition of the mercury(II) acetate to the alkene, formation of a mercurinium ion intermediate, addition of the alcohol, and subsequent reduction with NaBH₄.
