摘要:尽管苯并三唑是重要的且无处不在,但目前仅有一种概念上的合成方法:将两个邻氨基与亲电氮原子桥连.在此,我们公开了新的可行的选择-将内获得2 Azidoaryl Lithiums-Cyclization原位从2 Azidoaryl溴化物.使用二十四个带有各种烷基,烷氧基,全氟烷基和卤素取代基的实例来说明反应的范围.我们发现叠氮化物基团的导向作用允许在含有几个溴原子的芳基叠氮化物中进行选择性的金属-卤素交换.此外,(2-溴苯基)重氮甲烷经历类似的环化以生成吲唑.因此,芳基锂的环化包含邻-X = Y = Z基团是合成芳族杂环的一种新的通用方法.Dft计算表明,观测到的内选择性适用于经历" 1,1-加成"(即叠氮化物,重氮化合物和异腈)的其他官能团的阴离子环化反应.与此相反,与遵循"1,2-加成"图案(氰酸酯,硫氰酸酯,异氰酸酯,异硫氰酸酯,和腈)的杂原子官能团的环化反应倾向于外-Cyclizat

权利人:TRIAD NAT SECURITY LLC
摘要:Processes for tailoring the macroscopic shape, metallic composition, mechanical properties, and pore structure of nanoporous metal foams prepared through combustion synthesis via direct write 3D printing of metal energetic ligand precursor inks made with water and an organic thickening agent are disclosed. Such processes enable production of never before obtainable metal structures with hierarchical porosity, tailorable from the millimeter size regime to the nanometer size regime. Structures produced by these processes have numerous applications including, but not limited to, catalysts, heat exchangers, low density structural materials, biomedical implants, hydrogen storage medium, fuel cells, and batteries.

摘要:Synthesis of triazole- and/or triazolium-based polymers is disclosed. Chemical Mechanical Planarization (CMP) slurries comprise abrasives; activator; oxidizing agent; additive comprising triazole- and/or triazolium-based polymers; and water. The use of the synthesized triazole- and/or triazolium-based polymers in the CMP slurries reduces dishing and erosion in highly selective tungsten slurries.

标 题:Process for the preparation of pure tolutriazoles
发明人：GENGNAGEL KURT; PAPENFUHS THEODOR
权利人:HOECHST AG
摘要:The process for the preparation of tolutriazoles by diazotation of toluylene-o-diamines and subsequent ring closure to form the tolutriazole ring, was improved and the tolutriazoles are now obtained in a simpler way and in a pure form. The improvement comprises dissolution of the tolutriazoles without preceding isolation after their synthesis by means of an alkaline agent, preferably a sodium hydroxide solution of 20 - 33% strength, and subsequent precipitation at a pH of from 4.5 to 6 by addition of a mineral acid, preferably nitric acid or hydrochloric acid, and avoids a subsequent technically complicated and expensive purification process as well as the use of organic solvents. The tolutriazoles obtained according to this novel process are sufficiently pure for the use as corrosion inhibition.
