Summary: | 碩士 === 輔仁大學 === 化學系 === 94 === This study describes a facile synthesis on a series of pyridine-containing liquid crystalline compounds, 2-(4’-alkoxyphenyl)-5-cyanopyridines. Preparation of these subject liquid crystals was completed in a sort two-step reactions, the addition of 4-alkoxyphenylmagnesium bromides to N-phenyloxycarbonyl-3-cyanopyridinium chloride afford a 1,2-dihydropyridine, which was then oxidized by o-chloronil. The resulted products, 2-(4’-alkoxyphenyl)-5-cyanopyridines, were obtained in good yields.
