【Abstract】 The carbanions derived from nitroalkanes can be easily oxidized into aldehydes or ketones by perfluorodiacyl peroxides in F₁₁₃（CCl₂FCCIF₂）at room temperature. Product studies strongly support that the reaction involves an initial electron transfer step, and we believe that the major product-aldehyde or ketone comes from 1, 2-elimination of unstable intermediate which is formed by cage combination of the nitroalkane radical and the perfluoroaeyloxy radical. As to the formation of the coupling products, R_F-R_F and vicinal dinitro compound are the direct evidences of the generation of acyloxy radical （de carboxylates fast to·R_F） and nitroalkane radical in the electron transfer step only. This reaction may serve as a new synthetic route from nitroalkanes to aldehydes or ketones. The formation of perfluoronitrosoalkanes in the reactions is also discussed.更多还原
