A copper-catalyzeddecarboxylative elimination reaction of (hetero)aromatic propionic acids to vinyl (hetero)arenes has been developed. This method furnishes alkenes from carboxylicacids without the need for stochiometric Pb or Ag additives or expensive or specialized photocatalysts. A series of mechanistic experiments indicate that the reaction proceeds via benzylic deprotonation and subsequent radical
已经开发了铜催化的(杂)芳族丙酸到乙烯基(杂)芳烃的脱羧消除反应。该方法无需化学计量的 Pb 或 Ag 添加剂或昂贵或专门的光催化剂即可从羧酸中提供烯烃。一系列机理实验表明,该反应通过苄基去质子化和随后的自由基脱羧进行;一种不同于涉及相关脱羧消除反应的单电子转移机制的途径。

A liquid crystal alignment agent allowing formation of an LCD element having good reliability and less residual image, a liquid crystal alignment film, and an LCD element having the liquid crystal alignment film are shown. The liquid crystal alignment agent includes a polymer (A), a photosensitive polysiloxane (B), and a solvent (C). The polymer (A) is obtained by reacting a mixture that includes a tetracarboxylic dianhydride component (a-1) and a diamine component (a-2). The photosensitive polysiloxane (B) is obtained by reacting a polysiloxane (b-1) having an epoxy group with a cinnamic acid derivative (b-2) and an aromatic heterocyclic derivative (b-3) containing nitride, oxide or sulfide.
