Hexaphenylbenzene exists as a mixture of enantiomers. As such, it is one of a few organic molecules that is chiral without having a chiral center. Remember that the only requirement for chirality is non-superimposability on its mirror image.
Explain how hexphenylbenzene is a chiral compound. I highly recommend that you build a model to see the answer.
The following reaction is carried out in the laboratory:
Explain what is going on in this reaction (provide mechanistic interpretation)?
What other reagent could replace the cyclic sulfone (known commonly as "sulfolene") ?
Why is sulfolene the preferred reagent to use in the lab instead of the other reagent you proposed above? (hint: compare the physical properties of these two reagents).
For the last few reports, you have been evaluating "real" spectra. In each case, peaks for the solvent used have appeared. In the carbon spectra (all run in CDCl3 so far), the solvent appears as three peaks. But CDCl3 has only one carbon, not three. Explain.
