  公开（公告）日：2003-11-13

  A photoactive compound is used in combination with a photosensitizer, represented by the following formula (1): A −[( J ) m −( X-Pro )] n (1) wherein A represents a hydrophobic unit comprising at least one kind of hydrophobic groups selected from a hydrocarbon group and a heterocyclic group, J represents a connecting group, X-Pro represents a hydrophilic group protected by a protective group Pro which is removable by light exposure, m represents 0 or 1, and n represents an integer of not less than 1. The protective group Pro may be removable by light exposure in association with the photosensitizer (especially, a photo acid generator), or may be a hydrophobic protective group. The hydrophilic group may be a hydroxyl group or a carboxyl group. The photoactive compound has high sensitivity to a light source of short wavelength beams, for resist application, therefore, the photoactive compound is advantageously used for forming a pattern with high resolution.

  一种光活性化合物与光敏剂结合使用，由以下公式（1）表示： A −[( J ) m −( X-Pro )] n (1) 其中，A代表至少包括一种从烃基和杂环基中选择的疏水基的疏水单元，J代表连接基团，X-Pro代表由光照可去除的保护基团Pro保护的亲水基团，m代表0或1，n代表不少于1的整数。 保护基团Pro可以与光敏剂（特别是光酸发生剂）一起通过光照可去除，也可以是疏水保护基团。亲水基团可以是羟基或羧基。光活性化合物对短波长光源具有很高的敏感性，用于光刻应用，因此，该光活性化合物有利于形成具有高分辨率的图案。

  Abstract The synthesis and structural characterization of five O -thiocarbamatephenols, 4 – 8 , are reported. These proligands were synthesized from Na mono-substituted bis(phenolate) complexes 1 – 3 , and used to obtain Al(III), Ga(III) and Zn(II) complexes, 9 – 17 . All compounds were characterized by multinuclear NMR and IR spectroscopies, mass spectrometry and, where possible, by single crystal

  Lewis‐acid catalysis and electrochemistry represent two powerful fields that have found widespread application in organic chemistry. Reported herein is an asymmetric electrosynthesis in combination with a chiral Ni catalyst leading to an intermolecular alkylation reaction in good yields with excellent enantioselectivities (up to 97 % ee). Mechanistic studies suggest that the Lewis‐acid‐bound radical

  路易斯酸催化和电化学代表了两个在有机化学中得到广泛应用的强大领域。本文报道的是不对称电合成与手性Ni催化剂的组合，其以良好的收率和极好的对映选择性（高达97％ee）导致分子间烷基化反应。机理研究表明，单电子阳极氧化过程中与路易斯酸键合的自由基中间体会选择性地与苄基自由基发生反应，生成所需的加合物。
