Dispiro-1,2,4-trioxolanes by Ozonolysis of Cycloalkylidenecycloalkanes on Polyethylene

Griesbaum, Karl,Krieger-Beck, Petra,Beck, Johannes

, p. 391 - 396 (2007/10/02)

Ozonolyses of symmetrical (1b-d) and of unsymmetrical cycloalkylidenecycloalkanes (8a, b) afforded the dispiro-1,2,4-trioxolanes 4b-d and 9a, b, respectively.Their thermal decompositions gave mixtures of the cyclic ketones (3) and lactones (6).Photolysis afforded in addition to 3 and 6 the cyclic anhydrides 13, which are isomeric with the corresponding disoiro-1,2,4-trioxolanes.
