Thermal deazetation of difluoro- and tetrafluoro-2,3-diazabicyclo<3.2.0>hept-2-enes proceed via two parallel mechanistic pathways, one involving formation of a diradical via simple N2 loss, and the other proceeding via a retro-dipolar cycloaddition process.A key finding was the absence of isolation of a bicyclopentane product in the difluoro case.
