Chemiluminescence of imino-1,2-dioxetan formed from ketenimine and singlet oxygen
Abstract
The chemiluminescent properties of several imino-1,2-dioxetans prepared by the photosensitized oxygenation of ketenimines at –78 °C, indicate that the energy level of the transition state for their decompostion to the corresponding ketones and isocyanates is low and that the decomposition proceeds via a biradical mechanism.
