  铑（III）催化从偶氮苯和重氮化合物合成亚硝酸盐

  摘要：

  与重氮化合物偶合后，已实现了Rh（III）催化的偶氮苯的CH活化，从而提供了一种直接的方法来以高收率获得官能化的三氟甲烷磺酸。该协议的特点是无银温和的反应条件以及与各种官能团的相容性。偶联过程通过最初的Rh（III）催化的CH烷基化反应进行，随后是三氟甲磺酸锌介导的环化反应，其中三氟甲磺酸锌既充当路易斯酸又是三氟甲磺酸来源。

  A novel transfer material is disclosed. The transfer material comprises, at least, a support, and, thereon, an optically uniaxial or biaxial anisotropic layer and a photosensitive polymer layer. A novel process for producing a liquid crystal cell substrate is also disclosed. The process comprises, at least, [1] laminating a transfer material as set forth in any one of claims 1 to 11 on a substrate; [2] removing the support from the transfer material laminated on the substrate; and [3] exposing the photosensitive polymer layer disposed on the substrate to light.

  本发明公开了一种新的转移材料。该转移材料包括至少一种支撑材料，在其上有一层光学单轴或双轴各向异性层和一层光敏聚合物层。本发明还公开了一种生产液晶电池基板的新工艺。该工艺至少包括以下步骤：[1]将任一权利要求1至11所述的转移材料层压在基板上；[2]从层压在基板上的转移材料中去除支撑材料；[3]将放置在基板上的光敏聚合物层暴露在光线下。

  A process of producing a substrate for liquid crystal display device comprising an optically anisotropic layer, which comprises forming the optically anisotropic layer by a process comprising the following [1] to [3]: [1] preparing a substrate having a raw optically anisotropic layer; [2] subjecting the raw optically anisotropic layer to patterned exposures of two or more types having different exposure conditions to each other; [3] subjecting the substrate obtained after the exposure to a heat treatment at 80° C. or higher and 400° C. or lower. By the process, a substrate for liquid crystal display device which contribute to reducing viewing angle dependence of color of a liquid crystal display device can be easily produced.

  A laminated structure comprising, at least one optically anisotropic layer formed of a liquid crystalline composition comprising a compound having two or more types of reactive groups, and at least one photosensitive polymer layer. The laminated structure is useful for forming an optically anisotropic layer inside of a liquid crystal cell. The laminated structure is also useful for forming a liquid crystal cell substrate with an optically anisotropic layer having an optically compensating ability, inside of a liquid crystal cell.

  A transfer material comprising an optically anisotropic layer formed of a liquid crystalline composition comprising a monomer having an acidic group and/or a monomer which generates a monomer having an acidic group by an action of an acid or a base, and a photosensitive polymer layer, which is useful for forming an optically anisotropic layer in a liquid crystal cell, is provided. A process for easily producing a laminated structure having a patterned optically anisotropic layer, which comprises the following steps [1] and [2]: [1] subjecting the transfer material to patterned light exposure using photomask; and [2] removing the non-exposed parts of the transfer material by development with an aqueous alkaline solution, is also provided.
