Thermolysis of 7-alkylidenenorbornadienes 2 results in a retro-Diels-Alder cleavage to fulvenes and acetylene.A different mode of cleavage - into benzene and a carbene - is observed with such derivatives of 2 which carry ?- or ?-donor functions at C-8.The dependence of the reaction pathways on the nature of the substituent at C-8 is discussed on the basis of MO-calculations.
