Suzuki-Miyaura reaction of chloroarenes using Pd(PPh3) 4 as catalyst

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.

Brominated thiophenes as precursors in the preparation of brominated and arylated anthraquinones

Brominated anthraquinones can be synthesized directly from bromothiophenes when these are reacted with 1,4-naphthoquinones in the presence of meta-chloroperoxybenzoic acid. The bromoanthraquinones are versatile building blocks in the preparation of arylated anthraquinones and of extended π-systems with interspersed anthraquinone units.

Synthesis and Properties of Liquid Crystalline 4,4 -Dialkoxy-2'-Methyl-p-Terphenyls

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).
