Abstract:

The thermal unimolecular reaction of the 1-2-dioxetane ring system to generate electronically excited state carbonyl containing compounds is by far the most carefully and extensively studied of all chemiluminescent reactions. The mechanism for this intriguing transformation has been hotly debated by proponents of stepwise and concerted decomposition paths. The ammunition in this controversy ranges from purely theoretical calculations to experimental substituent, solvent, and isotope effects. Of pivotal importance to the dissection of the reaction path have been studies of kinetics and of excited state yields for variously substituted dioxetanes.
