  • Stereoselectivity in Pinacol-Homocoupling Mediated by Samarium Diiodide
    作者:Peter G�rtner、Max Knollm�ller、Joachim Br�ker
    DOI:10.1007/s00706-003-0061-x
    日期:2003.12.1
     The stereoselectivity of the pinacol-coupling of various substituted benzaldehydes mediated by samarium diiodide was investigated. The dependence of product-ratios, yields, and stereoselectivities on the substrate, the substrate-reagent-ratio, and the solvent is described.

  • Photochemistry of two diphenyl β,γ-enones and a series of methyl- and phenyl-substituted α-phenyl ketones
    作者:Margareth J. C. M. Koppes、Astrid M. Crabbendam、Hans Cerfontain
    DOI:10.1002/recl.19881071205
    日期:——
    The photochemistry of the diphenyl β,γ-enones 2 and 3 and the methyl- and phenyl-substituted α-phenyl ketones 4-9 has been studied, using mainly benzene as solvent. Irradiation of 2 with λ 300 nm leads to the 1,3-acyl shift (1,3-AS) product 17, relatively small amounts of the decarbonylation products 15 and 16, and the photo-oxidation products benzophenone (18) and the α,β-unsaturated aldehyde 19.
    已经研究了二苯基β,γ-烯酮2和3以及甲基和苯基取代的α-苯基酮4-9的光化学,主要使用苯作为溶剂。用λ300 nm辐照2会导致1,3-酰基转移(1,3-AS)产物17,相对少量的脱羰产物15和16以及光氧化产物二苯甲酮(18)和α ,β-不饱和醛19。1,3- AS产物直接照射17个收率15,16,18和19,但没有2。
  • Photochemical Action of Ethylorthoformate
    作者:AHMED MUSTAFA
    DOI:10.1038/162856a0
    日期:1948.11
    Ciamician and Silber1 showed that when an ethyl alcohol solution of benzophenone is exposed to sunlight, the alcohol is oxidized to aldehyde and the ketone reduced to benzpinacol ; in the place of ethyl alcohol, isopropyl alcohol has frequently been used2. A large number of benzophenone derivatives react in the presence of alcohols as above3.
    Ciamician 和 Silber1 发现,当二苯甲酮的乙醇溶液暴露在阳光下时,乙醇被氧化成醛,酮被还原成苯频哪醇;常用异丙醇代替乙醇2。大量的二苯甲酮衍生物在醇的存在下会发生上述反应3。
