Chapman, Robert D. published the artcileSelective syntheses of mono- and bis(2-fluoro-2,2-dinitroethoxy)alkanes. Scope of the utility of triflate intermediates, Recommanded Product: 2,3-Dibromo-2,3-dimethylbutane, the publication is Journal of Organic Chemistry (1988), 53(16), 3771-5, database is CAplus.
Displacement of the bromide in BrCH2CHMeOCH2CF(NO2)2 (I) cannot be effected by AgO3SCF3 because of the electroneg. vicinal alkoxide’s deactivating inductive effect on the primary bromine; however substituents in the secondary position are more labile with respect to nucleophile displacement. The scope of the utility of nucleophilic substitutions using homologous α,ψ-dibromoalkanes, Br(CH2)nCHMeBr (n = 1,2,3) and a vicinal dibromoalkane, MeCHBrCHBrMe, is reported. This approach produced a variety of new fluorodinitroethyl ethers, including the novel (O2N)2CFCH2OCH2CHMeOCH2CF(NO2)2, which possesses two electroneg. alkoxy substituents in a vicinal arrangement, from the fortuitous intermediate (O2N)2CFCH2OCH2CHBrMe (II) by way of anchimeric assistance in the reaction of BrCH2CHBrMe, also yielding I, the regioisomer of II. Typically, α,ψ- and α,ω-dibromoalkanes are distinctly stepwise in their 2 possible SN1Ag+ displacements of bromide by AgO3SCF3, a characteristic which allows selective incorporation of relatively nonnucleophilic alkoxy substituents via displacements of triflate intermediates.
