Halogen recoil following /n, / reaction has been studied in some heterocyclic systems. The organic yields are
60% for irradiation as solids: exceptions are dioxanide furoate /34%/ and 5-chloro isatoic anhydride /31%/. As solutions in 1
1 THF + benzene and 1
1 HTF+DMSO, these yields are lower by
10% and decrase further when only THF is the solvent. Mass-spectroscopy data revealed the possible fragmentation pattern.
