  New Liquid Crystalline Compounds Involving Ester-Chalcone Linkages Having 1,3,5-Trisubstituted Pyrazole as a Terminal Group

  摘要：

  Mesogens with chalcone central linkage are rare. It has been observed that -CO-CH=CH- linkage is less conducive to mesomorphism compared to -CH=N-(azomethine), -COO- (ester), -N=-(azo) linkages due to the non linearity and angle strain arising from the keto group. But when -CO-CH=CH- linkage is present with other central linkages it becomes condusive to mesomorphism. In the present investigation two homologous series were synthesized having chalcone as a one of the central linkage. The homologous series have been derived from 1,3,5-trisubstituted pyrazole, p-hydroxy acetophenone, and alkoxy acid. Viz. 4(4 '-n-alkoxybenzoloxy) phenyl-propane-3-one(1-phenyl-3-methyl-2-pyrazoline-5-one) [series-I] and 4(4 '-n-alkoxybenzoloxy) phenyl-propane-3-one(1-phenyl(4 ''-methyl)-3-methyl-2-pyrazoline-5-one) [series-II].

• Transesterification for Synthesis of Carboxylates Using Aldehydes as Acyl Donors via C–H and C–O Bond Activations
  作者：Yong-Sheng Bao、Chao-Yue Chen、Zhi-Zhen Huang

  日期：2012.9.21

  A new type of transesterification between aryl, heteroaryl, alkyl N-heteroarene-2-carboxylates and various aldehydes by C–H and C–O bond activations has been developed for the synthesis of versatile carboxylates. A possible mechanism containing oxidative addition of acyl–O bond in parent ester and radical cleavage of sp2 C–H bond in aldehyde is proposed.

  The selective cleavage of common linkages in lignin polymers is a promising approach to generate valuable aromatic hydrocarbons. Herein, we found that on oxidation of Cα and Cγ hydroxyl groups in β-O-4 lignin model compounds with TEMPO catalyst resulted in the formation of 1,3-dicarbonyl TEMPO adduct. These oxidized products readily underwent fragmentation at Cα–Cβ bond in the presence of a catalytic

  木质素聚合物中常见键的选择性裂解是产生有价值的芳烃的有前途的方法。在此，我们发现用TEMPO催化剂氧化β-O-4木质素模型化合物中的Cα和Cγ羟基会导致1,3-二羰基TEMPO加合物的形成。这些氧化产物在催化量的酸存在下很容易在Cα–Cβ键处发生断裂，从而生成相应的羧酸和酚单体。
