Carbene formation, hydrogen migration, and fluorescence in the excited states of dialkyldiazirines
摘要:
Photolysis of 3,3-dimethyldiazirine produces an electronically excited singlet state which decays by at least three competitive pathways: (1) fluorescence, (2) nitrogen extrusion and carbene formation, and (3) alpha-hydrogen migration and propylene formation concurrent with nitrogen extrusion. The temperature dependence of the fluorescence intensity was determined.
