  1. 
                                Ru(bipy)32+ was a competent catalyst for intermolecular, but not intramolecular, Diels–Alder cyclizations .                            
    2.

                                Similarly, electron-rich styrenes participate in intra- or intermolecular Diels–Alder cyclizations via a radical cation mechanism.

                                Since isomerization of Δ1THC to virtually inactive Δ6THC takes place readily in acid or upon heating, the cyclizations must be carefully controlled.

                                While Ru(bipy)32+ proved to be a competent catalyst for intramolecular cyclizations using methyl viologen, it could not be used with molecular oxygen as an electron sink or for intermolecular cyclizations.
