| Abstract: | The novel alkali metal peroxide derivatives (CH3) 3COOC(CF3) 2ONa, NaOC(CF3) 2OOC(CF3) 2ONa and CF3C(O) OOC(CF3) 2ONa have been prepared through reactions of hexafluoroacetone, (CF3) 2CO, with the sodium salts of various organic hydroperoxides. These new salts are soluble in water and polar organic solvents and have been used to prepare the new covalent fluorocarbon/hydrocarbon peroxides (CH33COOC(CF3) 2OC(O)C6H5, (CH3) 3SiOC(CF3) 2-OOC(CF3) 2OSi(CH3) 3, and (CH33COOC(CF3) 2C(O)CF3] through reaction with compounds having active halogen. Although the new peroxides are apparently less flammable and explosive than their hydrocarbon analogs, they also exhibit shorter half-lives than the parent compound (i.e., the peroxide without hexafluoroacetone insertion). |
