We found that the hydrotrioxide of benzaldehyde is formed in an exothermic reaction involving the 1,3-dipolar insertion of ozone into the C-H bond of benzaldehyde. This intermediate forms benzoic acid and singlet oxygen. Because of the low barrier for the formation of hydrotrioxide this intermediate is not observed. A theoretical investigation of the involvement of still another intermediate, a cyclic tetraoxide formed as a primary product in the 1,3-dipolar cycloaddition of ozone to the carbonyl group of the aldehyde was also investigated.

The paper describes the behavior and properties of the two important halogenating reagents, N-bromo and N-iodosaccharin. Halogen atoms in these compounds are strongly electropositive and yield EDA complexes with Lewis bases with nitrogen or oxygen donor atom. Complexes with nitrogen donors are generally stronger and those of N-iodosaccharin are more stable than those of bromosaccharin. Complexes were characterized by NMR, X-ray diffraction and modelled by quantum chemical calculations.
