Mechanism of hexadehydro Diels Alder

Thomas Hoye and co-workers reported in JACS on a substituent effect on the rate of the hexadehydro-Diels Alder reaction. Unlike the regular Diels-Alder reaction, electron-withdrawing groups slowed the reaction down suggesting a step-wise diradical mechanism as opposed to a concerted mechanism.
