Abstract

Abstract Spiroozonides of tropones undergo an unusually facile fragmentation via the coarctate Möbius transition state 1. The ozonides are generated from formaldehyde O-oxide and tropone derivatives at− 90 C. Depending on the substitution, they fragment at temperatures between− 60 to+ 50 C to give carbon dioxide, formaldehyde, and benzene derivatives.
