Dispiro‐1,2,4‐trioxolane durch Ozonolyse von Cycloalkylidencycloalkanen auf Polyethylen

Abstract

Dispiro‐1,2,4‐trioxolanes by Ozonolysis of Cycloalkylidenecycloalkanes on Polyethylene 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 ). Photolyses afforded in addition to 3 and 6 the cyclic anhydrides 13 , which are isomeric with the corresponding dispiro‐1,2,4‐trioxolanes.
