• Metal cation-exchanged montmorillonite (Mn+-mont)-catalysed aromatic alkylation with aldehydes and ketones
  作者：Jun-ichi Tateiwa、Ei Hayama、Takahiro Nishimura、Sakae Uemura

  DOI：10.1039/a701744h

  日期：——

  The alkylation of aromatic compounds with aldehydes and ketones in the presence of a variety of metal cation-exchanged montmorillonites (Mn+-mont; Mn+ = Zr4+, Al3+, Fe3+, Zn2+, H+, Na+) has been investigated. Al3+- and Zr4+-Monts are revealed to be effective as catalysts, while no reaction takes place with Na+-mont. Al3+-Mont-catalysed alkylation of phenol with several aldehydes produces mainly or almost solely the corresponding gem-bis(hydroxyphenyl)alkanes (bisphenols) in good yields, while that with several ketones affords selectively the corresponding alkylphenols in moderate to good yields. The alkylation always occurs at the carbonyl carbon without any skeletal rearrangement and the kind of products depends much on the steric hindrance of an electrophilic intermediary carbocation. The alkylation of anisole, veratrole and p-cresol proceeds well, while that of toluene, benzene, chlorobenzene and nitrobenzene scarcely occurs.

  在各种金属阳离子交换的蒙脱石（Mn+-mont；Mn+ = Zr4+、Al3+、Fe3+、Zn2+、H+、Na+）存在下，研究了芳香化合物与醛和酮的烷基化反应。发现Al3+和Zr4+蒙脱石是有效的催化剂，而Na+蒙脱石则不发生反应。由Al3+蒙脱石催化的苯酚与几种醛的烷基化反应主要或几乎只生成了相应的双（羟苯基）烷烃（双酚），产率良好；而与几种酮的烷基化反应则选择性地生成了相应的烷基苯酚，产率适中至良好。烷基化总是发生在羰基碳上，没有骨架重排，产物的类型很大程度上取决于亲电中间体的碳正离子的空间位阻。茴香醚、邻苯二甲醚和对甲酚的烷基化反应良好进行，而甲苯、苯、氯苯和硝基苯的烷基化反应几乎不发生。

  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。
