  Synthesis and Mesomorphic Properties of Some Liquid Crystals with 2,3,5,6-Tetrafluorophenylene Unit

  摘要：

  Nine fluorosubstituted liquid crystals have been synthesized and their mesomorphic properties have been studied by texture observation in a polarizing microscope and confirmed by DSC. They show enantiotropic smectic A and nematic phases. The effect of terminal and lateral fluorosubstitution is also discussed.

  the pharmacological importance of ortho-arylbenzylamines, however, effective ortho-C-C bond formation of free primary and secondary benzylamines using PdII remains an outstanding challenge. Presented herein is a new strategy for constructing ortho-arylated primary and secondary benzylamines mediated by carbon dioxide (CO2). The use of CO2 with Pd is critical to allowing this transformation to proceed
