  • Highly Efficient Oxidative Bromination of Alkanes with the HBr-H2O2 System in the Presence of Catalyst
    作者:Yujin Li、Jie Ju、Jianhong Jia、Weijian Sheng、Liang Han、Jianrong Gao
    DOI:10.1002/cjoc.201190016
    日期:2010.12
    straight‐chain alkanes were efficiently brominated with an aqueous HBr‐H2O2 system. This oxidative brominating process was promoted by catalysis and irradiation with light. The cycloalkanes were converted to the corresponding bromo‐cycloalkanes in moderate yields and the straight‐chain alkanes produced dominantly secondary bromides. This simple but effective bromination method of alkanes is characterized
    各种环烷烃和直链烷烃可通过HBr-H 2 O 2水溶液有效溴化。通过催化和光照射促进了该氧化溴化过程。环烷烃以中等收率转化为相应的溴代环烷烃,而直链烷烃则主要生成仲溴化物。这种简单而有效的烷烃溴化方法的特点是原子效率高,试剂价格便宜并且不存在有机废物,这使其成为现有的溴化CH活化方法的良好替代方法。

  • Catalytic distillation process for primary haloalkanes
    申请人:Shell Oil Company
    公开号:US08115039B2
    公开(公告)日:2012-02-14
    A process for making primary haloalkanes by catalytic distillation of internal haloalkanes which comprises a) introducing an internal haloalkane feed into a catalytic distillation column; b) isomerizing at least a portion of the internal haloalkane feed in the presence of an internal haloalkane isomerization catalyst at a temperature at or above the boiling point of the internal haloalkanes and below the temperature and pressure at which hydrogen halide is formed to form primary haloalkanes; and removing the primary haloalkanes from the catalytic distillation column.

  • Halide assisted addition of hydrogen halides to alkenes
    作者:Hilton M. Weiss、Kim M. Touchette
    DOI:10.1039/a703570e
    日期:——
    The addition of 0.1 M quaternary ammonium halide to a solution of 20% trifluoroacetic acid in methylene chloride causes a large rate increase in the reaction of simple alkenes leading to a mixture of alkyl halides and trifluoroacetates. The mechanism is proposed to involve a halide assisted protonation of the alkene which produces a carbocation intermediate sandwiched between the attacking halide ion
    向20%三氟乙酸的二氯甲烷溶液中添加0.1 M卤化季铵盐会使简单烯烃的反应速率大大增加,从而导致烷基卤化物和三氟乙酸盐的混合物。建议该机理涉及烯烃的卤化物辅助的质子化,其产生夹在进攻性卤化物离子和三氟乙酸根离子之间的碳正离子中间体。在较高浓度的卤化物离子下,溶液的质子给予能力降低,从而减慢了反应并提高了卤化物离子捕获阳离子的效率。这导致更大比例的未重排卤化物产物。在最高卤离子浓度下,几乎消除了阳离子重排。
  • B. anthracis prevention and treatment: mutant B. anthracis lacking luxS activity and furanone inhibition of growth, AI-2 quorum sensing, and toxin production
    申请人:Jones B. Marcus
    公开号:US20050042634A1
    公开(公告)日:2005-02-24
    The present invention pertains to the discovery that B. anthracis possesses a luxS gene that encodes a functional LuxS polypeptide, and that B. anthracis synthesizes a functional AI-2 quorum-sensing molecule. The invention provides mutant B. anthracis bacteria lacking the function of the luxS gene, which do not produce a functional AI-2 molecule and have growth defects compared to wild-type B. anthracis . The invention also concerns methods for inhibiting the growth of B. anthracis , or for preventing or treating B. anthracis infection, by inhibiting the activity of the B. anthracis LuxS polypeptide, or by exposure of the B. anthracis to furanone. In particular, the invention concerns the use of furanone, a compound that inhibits AI-2-mediated quorum-sensing, to inhibit the growth of B. anthracis , to inhibit B. anthracis toxin production, particularly that of protective antigen, and to prevent or treat B. anthracis infection. The invention also provides methods to prevent B. anthracis infection, or enhance an immune response to B. anthracis infection, by administering a vaccine comprising a B. anthracis cell in which the luxS gene is mutated.
    本发明涉及发现B. anthracis具有编码功能性LuxS多肽的luxS基因,以及B. anthracis合成功能性AI-2类群体感应分子。该发明提供了缺乏luxS基因功能、不产生功能性AI-2分子并与野生型B. anthracis相比具有生长缺陷的突变B. anthracis细菌。本发明还涉及通过抑制B. anthracis LuxS多肽的活性或暴露于呋喃酮来抑制B. anthracis的生长,预防或治疗B. anthracis感染的方法。特别是,本发明涉及使用呋喃酮,一种抑制AI-2介导的类群体感应的化合物,来抑制B. anthracis的生长,抑制B. anthracis毒素的产生,特别是保护性抗原的产生,并预防或治疗B. anthracis感染。本发明还提供了通过给予包含luxS基因突变的B. anthracis细胞的疫苗来预防B. anthracis感染或增强对B. anthracis感染的免疫反应的方法。
