The maximum value of the rate constant of the intermediate carbocation decay and the formation of oligomeric products in the photolysis of 1,2,2,3-tetramethyl-1,2-dihydroquinoline () in the TFE-H2O mixture 3 : 7 (v/v) were accounted for by the formation of a pseudo-phase of TFE clusters, where the molecules of 1 are concentrated, and the carbocations are generated. TFE, H2O, and compete in the combination reaction with the carbocation.

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.
