4. How might you prepare the following substances by using nucleophilic substitu- tion reactions? (a) CH3CH2CH2CH2OH (b) (CH3)2CHCH2CH2N3
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.
