摘要:我们意外地发现氯铝酸盐离子液体可以在令人惊讶的温和条件下裂解芳香族甲基醚.三种离子液体,即.[tmah][al2Cl7],[bmim][al2Cl7],[emim][al2Cl6I] 和氯化铝在 4-甲氧基官能团的 4,5-二甲氧基茚满酮的选择性去甲基化中进行了比较.与氯化铝 (70:30) 相比,离子液体表现出非常高的选择性 (96:4).此外,当使用离子液体时,反应时间大大缩短.有趣的是,这三种离子液体在 4,5-二甲氧基茚满酮的去甲基化反应中表现出相同的反应性.考虑到 [tmah][al2Cl7] 前体的较低成本和大量可用性,我们得出结论,从工业角度来看,这是最具吸引力的离子液体.为了使 [tmah][al2Cl7] 的大规模应用可行,我们开发了一种安全的,可升级的制备方法.此外,研究了离子液体试剂[tmah][al2Cl7]对醚裂解的范围,发现芳香甲基-,烯丙基-和苄基-醚裂解适用于多种杂环化合物.(©

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.

摘要:The invention relates to a process for the synthesis of aryl alkyl monoethers by reaction of a phenol compound, comprising one or more hydroxyl groups attached to the aromatic system, and of a dialkyl carbonate. It is a solvent-free process carried out at a pressure of between 0.93x10<5 >Pa and 1.07x10<5 >Pa, at a temperature of between 100° C. and 200° C., and in the presence of a catalyst chosen from the group consisting of alkaline carbonates and alkaline hydroxides. The dialkyl carbonate is added gradually to the reaction mixture.
