N-chloro-N-methyl-p-toluensulfonamide is a particularly chlorinating agent. The kinetic behaviour has been studied in the formation reaction of N-chloramines using ten nitrogenous compounds.

In small molecule models of stimuli-induced degradable polymers, less aromatic releasing units provide faster rates of azaquinone methide-mediated release of benzylic phenols than highly aromatic releasing units.

7-R-9-ethyl-6,9-dihydro-6-oxo-[1,2,5]selenadiazolo[3,4-h]quinolines and 6-ethyl-6,9-dihydro-9-oxo-[1,2,5]selenadiazolo[3,4-f]quinoline were synthesized and characterized by UV/vis, FT-IR and fluorescence spectroscopy; the generation of superoxide radical anions and singlet oxygen was monitored by electron paramagnetic resonance spin trapping technique and sterically hindered amine oxidation.

The electronic structure of Aristolochic acid (AA1) has been elucidated using the aug-cc-pVDZ level of theory, resulting in a potentially trapped resonance at the ring A which causes a localized electronic distribution, differentiating the first from the two other rings of the phenanthrene moiety of AA1. This property can play a significant role in its transformation pathways in biochemical and toxicological settings.
