摘要:在旋转限制的"geländer"低聚物的背景下,介绍并讨论了新型二乙炔桥连三联苯大环1 .丁二炔1的 1,4-双(苯基丁-1,3-二炔-1-基)苯桥明显长于其三联苯主链,迫使桥绕中心塔弯曲.分子1的合成在很大程度上基于乙炔支架策略,利用正交炔保护基团通过氧化乙炔偶联顺序封闭两个大环亚基.分析了双环目标结构1的空间排列和动态对映过程.深入的核磁共振研究不仅揭示了两条低聚物链沿着主链弯曲的意想不到的空间排列,而且还显示了模型化合物在分子氧存在下的有限稳定性.

标 题 :Synthesis of phenolic monomers containing imide or diimide moieties and high heat carbonate polymers prepared therefrom
发明人:AMERIK VALENTINA; HOEKS THEODORUS L; LIKIBI PARFAIT JEAN MARIE; NELSON MARK
权利人:GEN ELECTRIC
摘要:A process has been surprisingly discovered that can produce a high heat carbonate polymer (i.e., one with a Tg greater that 150° C.), without the drawbacks encountered in attempts to produce a high heat carbonate polymer. The process of the instant invention comprises the steps of: n (1) reacting an aromatic amine with a dihydric phenol to prepare an aminophenol; n (2) reacting an anhydride or dianhydride with the aminophenol to prepare a phenolic precursor; and n (3) reacting the phenolic precursor with a carbonate precursor to prepare a high heat carbonate polymer.

摘要:Representatives of 2-amino-N-(benzo[d]thiazol-2-ylsulfonyl)-3-hydroxybutanamide with general formula (I) show potency to inhibit malarial threonyl-tRNA synthetase (ThrRS) in low micromolar to nanomolar concentrations. As such they can be applied as compounds for prevention or treatment of malaria.

标题:Reclamation of bisphenol tars as feedstock in the synthesis of aminophenylhydroxphenylalkanes
发明人:LIKIBI PARFAIT J M
权利人:GEN ELECTRIC
摘要:The disclosure is of a process for recovering valuable by-products of the condensation of phenol and a ketone from a mother liquor obtained for example upon crystallization of a 1:1 adduct of phenol and bisphenol, said mother liquor containing phenol, bisphenol, isomers, contaminant by-products of the condensation reaction of phenol with the ketone and acidic impurities. The mother liquor is distilled/evaporated leaving a tarry residue, which is the feedstock for the process of the invention. The recovery comprises heating the feedstock with proportions of an arylamine salt, to extract the bisphenol-A values as aminophenylhydroxylphenyl-alkanes.
