标题反应于室温在F_(113)(CClF_2CCl_2F)溶液中瞬间完成,产物经分析确定,该反应由硝基烷烃阴离子(R~1R~2CNO_2)向全氟酰基过氧化物(R_FCO_2)_2的单电子转移的决速步骤,生成全氟羧酸盐,全氟酰氧基自由基之脱羧偶合产物R_F—R_F(1)及硝基烷烃自由基偶合产物DN(2);但主要的产物是自由基笼内结合所生成的中间体立即发生1,2-消除得到的醛或酮.本文提供了一个由硝基烷烃合成相应醛和酮的新反应。
The title reaction was completed instantaneously in a solution of F 113 CClF 2 CCl 2 F at room temperature. The reaction was confirmed by the analysis of the single an electron of the perfluoroacyl peroxide (R_FCO_2) _2 from the nitroalkane anion (R ~ 1R ~ 2CNO_2) (1) and nitroalkane radical coupling product DN (2); however, the main products are free radicals Elimination of aldehydes or ketones by 1,2-elimination occurs immediately in conjunction with the resulting intermediates in the cage.This article provides a new reaction for the synthesis of the corresponding aldehydes and ketones from nitroalkanes.
