摘要：
The kinetics and mechanisms of the reactions of singlet perfluoro-4-biphenylnitrene and N-propyl-4-nitreno-2,3,5,6-tetrafluorobenzylamide with various amines, pyridine, and dimethylsulfoxide were studied by laser flash photolysis. The reactions of singlet arylnitrenes with amines are two-step processes. The primary step of the process is adduct formation; the rate constant of this reaction is high and lies within the range 4 × 107–2 × 108l mol–1s–1for the tested secondary amines. The second step (1,2-hydrogen shift) was accelerated in the presence of water.
