pyrolysis this intermediate could be trapped by dipolarophiles acting as a 4π as well as 8π dipole. It was observed that with dimethylacetylenedicarboxylate the 1,3-dipolar cycloadduct was the major product whereas with N-substituted maleimides the major product results from the addition across the 1,7-position. FMO analysis of the cycloadditions corroborated the rationalization of the observed reactivity
