  • Regioselective Preparation of Allylgermanes
    作者:Jun-ichi Yamaguchi、Yoshitake Tamada、Takeshi Takeda
    DOI:10.1246/bcsj.66.607
    日期:1993.2
    Allylgermanes were obtained by the reaction of allyl acetates with bis(triethylgermyl)cuprate(I) reagent in high yields. It was found that the present reaction proceeded with high regioselectivity, in which a triethylgermyl group was exclusively introduced to the less substituted side of an allylic system regardless of the original location of acetoxyl group. In the case of the allyl acetates possessing two secondary centers at the both ends of the allylic system, the formal SN2 product was preferentially produced (SN2 : SN2′ = ca. 9 : 1). The desulfurizative germylation of allyl phenyl sulfides utilizing bis(triethylgermyl)cuprate(I) reagent also proceeded to give allylgermanes in good yields with the same regioselectivity.
    通过将烯丙基醋酸酯与双(三乙基锗基)铜(I)试剂反应,可以获得高产率的烯丙基锗化合物。研究发现,该反应具有高区域选择性,即三乙基锗基团独占性地引入到烯丙基体系的较少取代侧,而不受醋氧基团原始位置的影响。在烯丙基体系两端都拥有两个二级中心的烯丙基醋酸酯的情况下,形式上优先生成SN2产物(SN2 : SN2′ ≈ 9 : 1)。利用双(三乙基锗基)铜(I)试剂对烯丙基苯基硫化物进行去硫化锗化反应,也能以良好的产率生成烯丙基锗化合物,并且保持相同的区域选择性。

    (Li[PhnMe3-nSiBPh3], n = 1−3) and germylborates (Li[PhnMe3-nGeBPh3], n = 1−3; M[Et3GeBPh3], M = Li, Na, K) were prepared by the reaction of the corresponding silyl- and germylalkali metals with triphenylborane in a hexane/benzene mixed solvent. The silyl- and germylborates were fully identified by 1H, 13C, 11B, and 7Li NMR spectroscopic methods. The solid-state structure of germylborates Li[Ph3GeBPh3] and

    Abstract Aluminium alkoxides are shown to prominently influence the selectivity of reactions involving a single electron transfer (SET) stage. Triethylgermyllithium (I) reacts with amides R2NC(O)X (II) (X = Cl, OMe, NMe2, Ph) by a mechanism which includes a free-radical stage. The radical anion salt of N,N-diethylbenzamide, which is thermally stable in hydrocarbons, was detected. An efficient synthesis

    日期:1998.4.1
    Using the hydrogen abstraction reaction of triplet benzophenone with triethylgermane in an SDS micellar solution, we succeeded in enriching 73Ge with the magnetic isotope effect. At zero magnetic field, 0.5% enrichment of 73Ge was observed for the cage product (diphenyl(triethylgermyl)methanol). With increasing magnetic field strength (B), the enrichment of 73Ge increased initially, attaining the maximum
    利用三线态二苯甲酮与三乙基锗烷在 SDS 胶束溶液中的夺氢反应,我们成功地利用磁性同位素效应富集了 73Ge。在零磁场下,观察到笼状产物(二苯基(三乙基锗基)甲醇)的 73Ge 富集率为 0.5%。随着磁场强度(B)的增加,73Ge的富集最初增加,在500 G时达到最大值5.3%。在更高的磁场(500 G < B ≤ 10 kG)下,它逐渐减少,在10 kG时变为1.0% . 73Ge 富集的磁场依赖性可以通过弛豫机制来解释。

The first X-ray structure of a ß-ketoacylsilane, that of lithium enolate 2a, is reported and discussed. The UV-visible spectra of the lithium enolates 2 exhibits two new transitions: one absorption is “red” shifted
