摘要

Previous work suggested that the thermolysis* of 0-peroxylactones 1 affords the ketone 3 as major product via the 1 3 diradical 2, while photolysis3 leads predominantly to the epoxide 5 via the 1, 3 diradical 4 (eq 1). Herein we present 4 t experimental evidence for the tetramethyl-0-peroxylactone (la), which obliges us to modify this mechanistic interpretation. We postulate that in both decarboxylation modes 1, 5 diradicals 2 of different electronic ...
