The existence of the NIH shift was established by determining the major product obtained from rearrangement of the following arene oxide, in which a hydrogen has been replaced by a deuterium.
a. What would be the major product if the NIH shift occurs? b. What would be the major product if the carbocation forms phenol by losing H+ or D+, rather than by going through the NIH shift?
Explain the following result. Although alkenes are generally more reactive than alkynes towards electrophiles, the reaction of Cl2 with but-2-yne can be stopped after one equivalent of Cl2 has been added.
An inexperienced graduate student treated dec-5-ene with borane in THF, placed the flask in a refrigerator, and left for aparty. When he returned from the party, he discovered that the refrigerator was broken and that it had gotten quite warminside. Although all the THF had evaporated from the flask, he treated the residue with basic hydrogen peroxide. Tohis surprise, he recovered a fair yield of decan-1-ol. Use a mechanism to show how this reaction might have occurred.(Hint: The addition of BH3 is reversible.)

- The following bicyclic ketone has two -carbons and three -hydrogens. When this molecule is treated with D2O in the presence of an acid catalyst, only two of the three -hydrogens exchange with deuterium. The -hydrogen at the bridgehead does not exchange. How do you account for the fact that two -hydrogens do exchange but the third does not? You will find it helpful to build models of the enols by which exchange of -hydrogens occurs.arrow_forwardConversion of an alkene to a halohydrin and internal displacement of a halide ion by an alkoxide ion are both stereoselective.
