The reactivity of a number of chloroarenes was investigated and chloro-nitroarenes were found to undergo facile arylation with Pd(PPh 3)4 / [Pd(PPh3)2Cl 2/n.PPh3] as catalyst. Furthermore, 4-chlorobenzaldehyde underwent arylation under the conditions, albeit with a higher catalyst loading.

A new series of laterally substituted terphenyl compounds, 4,4 -dialkoxy-2'-methyl-p-terphenyls (n = 1-12), were synthesized. Their liquid crystallinities were characterized by means of polarizing optical microscopy (POM), differential scanning calorimetry (DSC), and X-ray difraction (XRD). The influence of the length of the terminal alkoxy groups on the liquid crystalline behavior was investigated. It was found that the compounds with shorter end chains (n a smectic A mesophase is exhibited for those with longer end chains (9 = n = 12).

The thioester unit has been commonly used to enhance the mesophase thermal stability and phase range in numerous liquid crystal materials. In this paper we report the synthesis of a homologous series of thioesters with similar structures to AS620 {(S)-(+)
