    Grafting Reaction of Organotin Complexes on Silica Catalyzed by Tungstic Heteropolyacids
    摘要:
    The grafting reaction of tetramethyltin on silica is catalyzed by H4SiW12O40 preliminary impregnated on the support. While the reaction proceeds at temperatures higher than 150 degrees C on silica alone, the presence of the polyacid allows the grafting at room temperature. A study as a function of the polyacid coverage has shown that there is a direct correlation between the reaction rate and the number of highly acidic sites on the support, probing that there is a reaction of the tetraalkyltin with them (limiting step) followed by a migration of the grafted fragment on the silica surface. Not only monografted species (as observed on silica) but also multigrafted tin species are formed because of further reactions of the grafted fragments.

    来自植物油的聚合物通过硅氧烷键连接进行程序解聚
    摘要:
    塑料产量的增加导致塑料废物的积累和有限的化石燃料资源的枯竭。在这种背景下,我们报告了一种通过将可再生原料与硅氧烷键连接来制造可以进行受控解聚的聚合物的策略。含有硅氧烷键的α,ω-二酯和α,ω-二醇是由蓖麻油衍生的烯酸酯合成的,然后与各种单体(包括相关的生物基单体)聚合。此外,制备衍生自该链烯酸酯和氢硅氧烷的环状单体并环化形成含有硅氧烷单元的26元大环内酯。这种大环内酯和丙交酯的连续开环聚合提供了 ABA 三嵌段共聚物。这组含有硅氧烷的聚合物在质子溶剂中或使用六甲基二硅氧烷和酸催化剂进行程序解聚成单体。将含有硅氧烷键的聚酯解聚得到的单体进行再聚合,以证明所选聚合物的环状性。对这些聚合物对酶降解的环境稳定性的评估表明,它们会被来自茄病镰刀菌的真菌角质酶进行酶水解。对13 C 选择性标记单体的土壤微生物代谢的评估揭示了土壤微生物对主链和侧链有机基团的不同代谢。

  • New and efficient synthetic routes to 1-deoxy-D-xylulose
    作者:José-Luis Giner
    DOI:10.1016/s0040-4039(98)00310-4
    日期:1998.4
    1-deoxy-D-xylulose was synthesized by improved methods. D-Tartaric acid is the starting material for a synthesis which proceeds via the intermediacy of 2,3,4-tribenzyl-D-threitol. Another, highly efficient route used the Sharpless asymmetric dihydroxylation of 5-benzyloxy-3-penten-2-one as its key step. These syntheses are especially useful for isotopic labeling.

    日期:1994.6
    l. Clear trends were observed; the dppp complexes were much more stable than the others, and the phenylpalladium complexes were more stable than their vinylpalladium counterparts. The observed trends fit with the idea that the reductive elimination step in palladium cross-coupling is facilitated by a ligand with a large interchelate angle. The dppr complexes were significantly more labile than their
    摘要在-30°C的环境温度下研究了一组原位生成的P 2 PdMeR型配合物的热稳定性,目的是确定配体咬角与还原反应活性之间的关系。消除。在该系列中,P 2是1,3-(二苯基膦基丙烷(dppp),1,1'-(二苯基膦基二茂铁(dppf)或1,1'-(二苯基膦基属(dppr),R为苯基或E -2-(4-甲氧基苯基)乙烯基。观察到明显趋势;dppp配合物比其他配合物稳定得多,苯基配合物比乙烯基配合物更稳定。观察到的趋势符合这样的想法:的交叉偶联中的还原消除步骤是通过具有大的螯合角的配体来促进的。
  • New Elements on the Behaviour of a Bissulfinylmethyl Radical

    In this article, we have studied the generation of a bissulfinylmethyl radical from the corresponding TEMPO and phenylselenyl bissulfoxide precursors. No univocal formation of the bissulfinylmethyl radical has been observed. Instead, complex mixtures have been obtained in thermal or photochemical conditions, showing prominent C–S homolytic bond cleavage.

    在本文中,我们研究了从相应的 TEMPO 和苯基基双亚磺酸前体中生成双亚磺酰甲基自由基的过程。我们没有观察到双亚酰基甲基自由基的单一形成。相反,在热或光化学条件下会产生复杂的混合物,显示出明显的 C-S 同解键裂解现象。
  • Rhodium-Catalyzed Hydroalkynylation of Internal Alkynes with Silylacetylenes: An Alkynylrhodium(I) Intermediate Generated from the Hydroxorhodium(I) Complex [Rh(OH)(binap)]2

    日期:2007.12.10
    A highly selective hydroalkynylation of internal alkynes with silylacetylenes giving 1,3-enynes was realized by use of a hydroxorhodium catalyst. As a key intermediate in the catalytic cycle, an alkynylrhodium(I) complex was isolated and investigated for its structure and reactivity.

  • The biosynthesis of caerulomycins in <i>Streptomyces</i> <i>caeruleus</i>. Isolation of a new caerulomycin and incorporation of picolinic acid and glycerol into caerulomycin A

    oxidation, implicating free picolinic acid as an intermediate in the pathway from lysine. The substituted pyridyl ring of caerulomycin was labeled by [2-13C, 1,3-14C]glycerol. 13C nuclear magnetic resonance analysis located the 13C predominantly at C-6, suggesting that C-5, C-6, and C-7 were derived from glycerol as an intact three-carbon precursor. Since no incorporation of [1-13C]glyceric acid was
    在蓝蓝链霉菌培养物中用 [U-14C] 赖生物合成标记的蓝蓝霉素 A 用高锰酸盐氧化,产生与抗生素具有相同比活性的吡啶甲酸。[3H] 吡啶甲酸以高效率掺入蓝霉素 A 中,并且在氧化后仅在吡啶甲酸中发现该标记,表明游离吡啶甲酸是赖酸途径中的中间体。蓝霉素的取代吡啶环被[2-13C, 1,3-14C]甘油标记。13C 核磁共振分析将 13C 主要定位在 C-6,表明 C-5、C-6 和 C-7 源自甘油作为完整的三碳前体。由于未检测到 [1-13C] 甘油酸的掺入且 [3-13C, 3-14C] 甲基乙二醛仅略微标记抗生素,这些化合物可能不是甘油生物合成中间体。从培养物中分离出一种具有醛取代醛取代基 C-6 的新型绿霉素。
