摘要：The mechanism and the synthetic applications for the oxidation of alcohols,
冬至古诗ethers, and aldehydes by H2O2 catalyzed by Br2 or Br- in a liquid two-pha system
(aqueous and organic) are reported. Aliphatic and benzylic primary alcohols and ethers
show an opposite behavior, which has been rationalized on the ground of the different黄焖全鸡
electronic configurations of the intermediate alkyl (π-type) and acyl (σ-type) radicals and
their influence on enthalpic and polar effects. A two-pha system is particularly uful手机卡丢了怎么补办
also for an efficient benzylic bromination by Br2 or Br-; the substitution of the benzyl
bromide by OH, OR, and OCOR regenerates Br-, which can be recycled. The evaluation of

the relative reactivities of the involved substrates and intermediates has allowed to
