  Magnesiation of Electron-Rich Aryl Bromides and Their Use in Nickel-Catalyzed Cross-Coupling Reactions

  摘要：

  Electron-rich aryl bromides are rapidly converted to the corresponding lithium triarylmagnesiates with (n-Bu)(3)MgLi, which undergo efficient nickel-catalyzed Kumada-Corriu cross-coupling reactions with a variety of aryl and alkenyl bromides, chlorides, tosylates, and triflates.

  In a lithium ion secondary battery according to one embodiment of the present invention, an electrode includes an electrode active material, a conductive auxiliary agent, and a binding material configured by a binding component that binds the conductive auxiliary agent and forms a conduction path between the electrode active material, and by a melting point depressant that lowers a melting point of the binding component. The melting point depressant is a PTC functionality-imparting component that lowers the melting start temperature of the binding material and imparts the PTC functionality to the lithium ion secondary battery. The lithium ion secondary battery according to the invention is configured such that, when short circuit heat generation has occurred within the battery due to a conductive foreign substance, the binding material at a periphery of the foreign substance melts to sever the conduction path.

  Provided are an alignment aid that sufficiently exerts an alignment control force causing liquid crystal molecules to be vertically aligned and can reduce a change in pretilt angle over time, a liquid crystal composition containing the alignment aid, and a liquid crystal display device. The alignment aid of the present invention has the function of causing the liquid crystal molecules to be aligned spontaneously. In the light absorption spectrum of the alignment aid, the longest wavelength at which the absorbance is 0.5 is 330 nm or shorter. Preferably, the light absorption spectrum is measured on a solution prepared by dissolving the alignment aid in tetrahydrofuran at a concentration of 1000 ppm.

  It is a method for manufacturing a liquid crystal display device in which an anchoring force causing liquid crystal molecules to be vertically aligned can be exerted sufficiently. A liquid crystal display device ( 1 ) including two substrates AM and CF and a liquid crystal layer ( 4 ) sandwiched therebetween can be manufactured. The liquid crystal display device manufacturing method includes: a first step of subjecting a surface of one of the substrates AM and CM that is to be in contact with the liquid crystal layer ( 4 ) to hydrophilization treatment; and a second step of disposing the two substrates AM and CF so as to face each other such that the two substrates are in contact with a liquid crystal composition containing liquid crystal molecules and an alignment aid having a polar group and having the function of causing the liquid crystal molecules to be aligned spontaneously.
