  • Bromination of ketones with the systems H2O2-LiBr-CeIII and H2O2-LiBr-CeIV
    作者:G. I. Nikishin、L. L. Sokova、N. I. Kapustina
    DOI:10.1007/s11172-013-0166-2
    日期:2013.5
    A new method for the synthesis of α-bromoketones was suggested. The C5-C11 linear and branched ketones in the reaction with the systems H2O2-LiBr-CeIII and H2O2-LiBr-CeIV in acetonitrile were brominated at α-position. The reaction is highly selective.
    提出了一种合成α-溴酮的新方法。在乙腈中与 H2O2-LiBr-CeIII 和 H2O2-LiBr-CeIV 系统反应中的 C5-C11 直链和支链酮在 α 位被溴化。该反应具有高度选择性。
  • Oxidation of secondary alkanols with the system cerium ammonium nitrate—lithium bromide into ketones, α-bromo ketones, and α,α′-dibromo ketones
    作者:G. I. Nikishin、L. L. Sokova、N. I. Kapustina
    DOI:10.1007/s11172-010-0091-6
    日期:2010.2
    Oxidation of secondary alkanols with the system Ce(NH4)2(NO3)6—LiBr in aqueous acetonitrile gave ketones, α-bromo ketones, or α,α′-dibromo ketones. The selectivity of the reaction under standard conditions depends only on the molar ratio of the reagents (alkanol: CeIV: LiBr).
    仲链烷醇在乙腈水溶液中用 Ce(NH4)2(NO3)6-LiBr 系统氧化得到酮、α-溴酮或 α,α'-二溴酮。标准条件下反应的选择性仅取决于试剂的摩尔比(烷醇:CeIV:LiBr)。
