// Very few successful cases have been reported with benzene as the
// diene in a Diels-Alder reaction due to its aromaticity
// It only reacts with very active dienophiles, or when the aromatic ring
// is heavily destabilitized by increasing ring strain
// Due to these considerations it is generally not reactive as a diene or
// dienophile, and certainly not with the general RMG rates.
