Diels–Alderreactions have been accomplished with ethylene as the dienophile through the use of inverse-electron demand Diels–Alder chemistry. As a key aspect of the chemistry, the dienes are part of tri- or dicationic superelectrophilic systems. Theoretical calculations reveal that the highly charged superelectrophiles possess exceptionally low lying LUMOs, and this facilitates the cycloaddition chemistry
