Synthesis and properties of di(polyfluoroalkyl) peroxydicarbonates

Synthesis of di(polyfluoroalkyl)peroxydicarbonates [X(CF2) nCH2OC(O)O]2, where X = H, F; n = 1, 2, 4, 6 (yield 80%) involves the step of the chloroformate formation (yield up to 93%) via the phosgenation of polyfluorinated alcohols followed by the reaction with sodium peroxide. The rate constant of monomolecular decomposition k term was found to decrease as the polyfluoroalkyl groups were incorporated into the peroxide: it equaled 3.30 and 3.10 s-1 for X = H, n = 2 and 4, respectively, and 7.36 s-1 for di-n- butylperoxydicarbonate. The new peroxides are a source of the polyfluoroalkoxy radicals and nano-modifiers of the polymers to improve their heat resistance and light stability. Pleiades Publishing, Ltd., 2011.

Herbicidal fluorinated carbonates

Fluorinated carbonates are described which are useful as miticides. These carbonates often possess herbicidal, insecticidal, and/or fungicidal properties. Examples of the fluorinated carbonates are 2',4'-dinitro-6'-sec-butylphenyl-2,2,2-trifluoroethyl carbonate; 2',4'-dinitro-6'-sec-butylphenyl-2,2,3,3-tetrafluoropropyl carbonate and 2',4'-dinitro-6'-cyclohexylphenyl 2,2,3,3-tetrafluoropropyl carbonate.
