标题:在温和条件下碲介导的无环烯二炔环芳构化
摘要:无环烯二炔的环芳构化通常需要非常高的温度(> 160 摄氏度)和稀释条件才能以合成有用的收率进行.这些条件阻碍了反应产量,抑制了该反应在材料的大规模生产中的应用.碲化钠与无环芳二炔反应生成相应的碲碱,在温和加热下会挤出 Te 度,生成环芳构化产物.我们已经开发出从廉价的碲金属原位形成碲化钠的条件,并在同一过程中对甲硅烷基化芳烃进行脱甲硅烷基化.在我们的条件下,我们能够在低至 40 摄氏度的温度和大至 5 克的标准实验室玻璃器皿中进行脱甲硅烷基化和环芳构化.

摘要:This disclosure refers to a method for the synthesis of polymers with weight average molecular weights greater than 50,000 g/mol, chemically inert, with a minimum decomposition temperature of 425° C., and a main chain composed only of carbon-carbon bonds, which contain structures of the type of naphthalene, phenanthrene, anthracene, pyrene, carbazole or any other where two or more aromatic rings of six carbon atoms of the benzene-type are fused, which may or may not contain aromatic heterocycles. In addition, the polymers obtained from the present disclosure may or may not contain fluorine atoms in their structure. The synthesis described here is carried out by means of polycondensation between a polycyclic aromatic compound and a compound with a carbonyl group in its structure in a strong acid medium.

摘要:The subject invention provides chemical compositions and synthesis strategies to create molecularly imprinted polymers (MIPs) via sol-gel processes. In a specific embodiment, the subject invention utilizes a(n) organic, inorganic, or metallic template analyte to create a hybrid organic-inorganic or inorganic three-dimensional network possessing cavities complementary to the shape, size, and functional orientation of the template molecule or ions. The subject invention further pertains to the use of the novel MIPs as selective solid phase extraction (SPE) sorbents for pre-concentration and clean-up of trace substances in biological and environmental samples. Synthesis of other molecularly imprinted polymers with environmental, pharmaceutical, chemical, clinical, toxicological, and national security implications can be conducted in accordance with the teachings of the subject invention.
