Selectivity in Lewis acid-mediated fragmentations of peroxides and ozonides: application to the synthesis of alkenes, homoallyl ethers, and 1,2-dioxolanes †
Aqueous-phase ozonolysis in the atmosphere is an important process during cloud and fog formation. Water in the atmosphere acts as both a reaction medium and a reductant during the ozonolysis. Inspired by the atmospheric aqueous-phase ozonolysis, we herein report the ozonolysis of alkenes in water assisted by surfactants. Several types of surfactants, including anionic, cationic, and nonionic surfactants

SnCl4-mediated reaction of ozonides (1,2,4-trioxolanes) with allyltrimethylsilane furnishes trimethylsilylmethyl-1,2-dioxolanes via metalated carbonyl oxides. The carbonyl oxides can arise through initial ionization of either the ether or peroxide oxygens.
