Expertise: Spectroscopy and Kinetics of Reactive Intermediates
Nitrenes, carbenes, silylenes, and germylenes
Our efforts have focused on the spectroscopy and reactivity of phosphoryl- and sulfonylnitrenes. Phosphorylnitrenes differ in their behavior from sulfonylnitrenes in that they are resistant to the photo-Curtius rearrangement. This simplifies the task of determining the reactivity of the triplet nitrene through laser flash photolysis.
Depending on the substituent, the photochemistry of the nitrene precursor sulfonyl azide is wavelength dependent. At short wavelengths, irradiation of 4-acetylbenzenesulfonyl azide yields products attributable to photo-Curtius rearrangement and the singlet and triplet nitrenes. At longer wavelengths, the rearrangement is suppressed, and only the sulfonamide arising from the triplet nitrene or triplet excited state azide are observed.
