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.
