A molozonide (or "molecular ozonide") is a 1,2,3-trioxolane, which can also be considered a cyclic disubstituted trioxidane derivative. Molozonides are formed by

cycloaddition In organic chemistry, a cycloaddition is a chemical reaction in which "two or more Unsaturated hydrocarbon, unsaturated molecules (or parts of the same molecule) combine with the formation of a cyclic adduct in which there is a net reduction of th ...
