  We present herein an unprecedented, efficient and enantioselective synthesis of triarylmethanes and 1,1‐diarylalkanes through N‐heterocyclic carbene‐catalyzed acylative desymmetrization of bisphenols. This method utilizes readily available substrates, reagents and a simple procedure to deliver the valuable products in excellent enantiopurity. DFT calculations reveal that the selectivity is governed

  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 molecular structures of nine eight-membered cyclic acetals containing two planar fragments in the ring, the derivatives of dibenzo- and dinaphtho[d,g][1,3]dioxocines, have been studied by x-ray single crystal diffraction. Steric interactions were found to determine the conformation realized in the crystalline phase. Depending on the type of planar fragments in the cycle and the group bridging

  摘要 通过 X 射线单晶衍射研究了环中含有两个平面片段的九个八元环状缩醛的分子结构，即二苯并 [d,g][1,3] 二恶辛的衍生物。发现空间相互作用来确定在结晶相中实现的构象。根据循环中平面碎片的类型和桥接它们的组，观察到船椅 (BC)、扭曲船 (DB)、扭曲 (T) 或扭曲船 (TB) 构象。6H,12H-dibenzo[d,g][1,3]dioxocine 的衍生物在苯并片段中含有甲基或在桥亚甲基中含有一个甲基取代基，发现了 BC 构象。T 和 TB 构象是通过羰基桥接平面片段的分子实现的。8H,16H-Dinaphtho[2,1-d,1'2'-g][1, 3]dioxocine 在所有包含两个萘并基的八元环状化合物中展示了 BC 构象的第一个例子，但其几何参数与其未受应变的值存在较大偏差。其他二萘并衍生物存在于 DB 构象中。讨论了分子几何结构和弱分子内CH⋯O氢键的可能性。
