Ozonolysis of tetramethoxyethene 1 produces 20-40% of dimethyl carbonate 3, 35-60% of methyl trimethoxyacetate 7, and 20-35% of the dioxetane 8 of 1. Yields vary with initial concentration of 1, temperature, and solvent. Singlet oxygen is produced, which reacts with 1 to form 8 and can be trapped with 2, 5-dimethylfuran. No evidence for the formation of the molozonide of 1 was obtained. Up to 2.5 moles of 1 are consumed per mole of ozone. ...
