    环境阴离子的反应性:烷基的硬度和环境阴离子烷基化中的共生效应
    摘要:
    据报道,在乙酰乙酸乙酯和乙酰丙酮阴离子的O-和C-烷基化的情况下,烷基化剂性质的影响。O / C比的值取决于三个因素:烷基化剂中烷基取代基的极性效应,烷基的空间效应和离去基团的共生效应。前两种效应的相对贡献取决于离去基团的性质。当离去基团为软碱(碘化物,溴化物,氯化物)且O / C比以秒为单位降低时,空间效应占主导地位。Bu> iPr> Et> Me。硬离去基团甲苯磺酸酯的情况与上述给定顺序相反的烷基顺序与烷基硬度的皮尔逊顺序相反。还报道了离去基团性质对O / C比的影响。发现离去基团对两种烯醇离子的甲基化都有很强的共生作用。在乙基化中,离去基团的作用较难检测到。对于两个仲烷基,O / C比对离去基团的性质几乎不敏感。

  • Ytterbium triflate catalyzed synthesis of β-keto enol ethers
    作者:Massimo Curini、Francesco Epifano、Salvatore Genovese
    DOI:10.1016/j.tetlet.2006.04.121
    日期:2006.7
    β-Keto enol ethers have been synthesized in very good yield in solvent-free conditions from differently substituted alcohols and β-diketones in the presence of Yb(OTf)3 as catalyst. The method is applicable to both cyclic and acyclic β-diketones with only slight differences in the experimental procedure.
    在无溶剂条件下,由Yb(OTf)3作为催化剂,由不同取代的醇和β-二酮以极高的产率合成了β-酮烯醇醚。该方法适用于环状和非环状β-二酮,在实验过程中仅稍有不同。

    公开号:US20090266877A1
    公开(公告)日:2009-10-29
    A method of enabling entry of data into a computer system via a printed substrate. The substrate has a surface containing human-readable information and machine-readable coded data. The coded data is indicative of an identity of the substrate and of a plurality of reference points on the surface. The method includes the steps of: operatively positioning a sensing device relative to the surface and sensing the coded data; generating indicating data using the sensed coded data; and sending the indicating data to a computer system. The coded data comprises an IR-absorbing dye having a nitrogen-substituted phthalocyanine.
