• Nucleophilic Substitution Reactions of Alkyl Halides by Using New Polymer-Supported Reagents Containing Hemin
  作者：Kiyoshi Saito、Kaoru Harada

  DOI：10.1246/bcsj.62.2562

  日期：1989.8

  hemin, divinylbenzene, and 2-methyl-5-vinylpyridine was synthesized by suspension copolymerization. Substitution reactions of primary, secondary, and tertiary alkyl halides with the hemin copolymer combined with cyanide, azide, and thiocyanate ions were given satisfactory yields. This reaction mechanism was revealed to be a SNi type on the basis of stereochemical study. The hemin copolymer was not only

  通过悬浮共聚反应合成了一种由氯化血红素、二乙烯基苯和2-甲基-5-乙烯基吡啶组成的新型高分子试剂。伯、仲和叔烷基卤与氯化血红素共聚物与氰化物、叠氮化物和硫氰酸根离子的取代反应得到了令人满意的产率。根据立体化学研究，该反应机理被揭示为 SNi 型。氯化血红素共聚物不仅是具有功能性的聚合物负载试剂，而且还用于将产物与反应混合物分离。

  A facile method to prepare difluoromethylenes, including α,α-difluorobenzyl chlorides, by single C–F transformations of benzotrifluorides is disclosed. The C–F cleavage followed by chlorination proceeded smoothly using trityl chloride through the generation of trityl cation as an activator and chloride anion as a nucleophile. Diverse difluoromethylenes such as difluorobenzyl ethers were efficiently

  A method and composition for identifying chemically tagged petroleum products can be achieved by adding one or more chemicals to a selected petroleum product wherein the chemical is immune to extraction from the petroleum product by conventional inexpensive absorbents, cannot be removed by extraction with acids, bases, or immiscible solvents, cannot be easily oxidized, reduced or reacted with common agents, is difficult to disguise by masking with other agents, has a low polarity, and has a boiling pint in the range of the petroleum product the chemical is being added to. The presence of the chemical is determined by using ion mobility to spectroscopy.

  通过向选定的石油产品中添加一种或多种化学物质，可以实现识别化学标记石油产品的方法和组合物，其中的化学物质不会被传统的廉价吸收剂从石油产品中萃取出来，不能被酸、碱或不溶性溶剂萃取去除，不容易被氧化、还原或与普通制剂发生反应，难以用其他制剂掩盖，极性低，沸点在所添加化学物质的石油产品范围内。化学品的存在是通过离子迁移率和光谱来确定的。
