herein is an electrochemical approach for the oxidative generation of benzynes (cyclohexyne) and its successful merging with chiral primary aminocatalysis, formulating the first catalytic asymmetric enamine–benzyne (cyclohexyne) coupling reaction. Cobalt acetate was identified to stabilize the in situ generated arynes and facilitate its coupling with an enamine. This catalytic enamine‐benzyne protocol

Novel hydrazines are disclosed in which one of the nitrogen atoms forms a ring member of the five membered ring of a [4.3.0] heterobicyclic compound which may be substituted elsewhere in the ring system. Characteristic ring systems described include indole and benztriazole ring systems. The compounds possess anti-depressant properties as well as anti-microbial, in particular fungistatic and bacteriostatic, properties.

The purpose of the present invention is to provide a nonaqueous electrolyte that contains acetonitrile having an excellent balance between viscosity and the dielectric constant and a fluorine-containing inorganic lithium salt, wherein the generation of complex cations comprising a transition metal and acetonitrile is suppressed, excellent load characteristics are exhibited, and increases in internal resistance upon repeated charge/discharge cycles are suppressed; a further purpose of the present invention is to provide a nonaqueous secondary battery. The present invention relates to a nonaqueous electrolyte which contains: a nonaqueous solvent comprising acetonitrile; a fluorine-containing inorganic lithium salt; and a specific nitrogenous cyclic compound typified by benzotriazole.
The present invention relates to a metal polishing liquid for polishing at least a part of metal in a substrate having the metal, comprising, component A: a metal solubilizer containing amino acids, component B: compounds having the benzotriazole skeleton, and component C: an acrylic acid polymer having the weight average molecular weight of 10,000 or more, and having the mass ratio between the component B and the component C, (component B:component C), to be 1:1 to 1:5. Use of the metal polishing liquid can simultaneously yield high polishing rates and low etching rates at higher level, enabling to form an embedded pattern with higher reliability.
本发明涉及一种金属抛光液,用于对具有金属的基体中的至少部分金属进行抛光,该抛光液由以下组分组成:组分 A:含有氨基酸的金属增溶剂;组分 B:具有苯并三唑骨架的化合物;以及组分 C:重量平均分子量在 10,000 或以上的丙烯酸聚合物,且组分 B 与组分 C 之间的质量比(组分 B:组分 C)为 1:1 至 1:5。使用金属抛光液可同时获得较高的抛光率和较低的蚀刻率,从而形成可靠性更高的嵌入图案。
