On the nature of diradical intermediates formed during the thermal and photochemical decomposition of bicyclic azo-compounds
Abstract
Direct and sensitized photodecomposition of exo- and endo-2-methyl-3,4-diazabicyclo[3,3,0]oct-3-enes proceeds through singlet and triplet diradical intermediates, but predominant single inversion of configuration in the products formed on thermal decomposition indicates a more complex mechanism.
