摘要
以2-氨基-3-取代的苯甲酸为起始原料,经重氮化-自偶联反应、酯化、还原、氧化、环合反应制备了4,5-二取代的菲衍生物,并以还原后的联苯中间体为原料经溴化、格氏化反应制备了4,5-二取代的9,10-二氢菲衍生物,以4,5-二取代的菲和4,5-二取代的9,10-二氢菲衍生物为原料经过卤化、偶联反应制备了液晶单体化合物.产物结构经过了1H NMR,13C NMR的确证,并对其性能进行了测试.研究结果表明,这类液晶具有较大的光学各向异性和介电各向异性.
Using 2-amino-3-substituted benzoic acid as starting material, 4,5-disubstituted phenanthrene derivatives were synthesized via sequential reactions of diazotization-coupling reaction, esterification, reduction, oxidation and cyclization, and using reduced biphenyl intermediates as starting materials. 4,5-Disubstituted 9,10-dihydrophenanthrene derivatives were synthesized via sequential reactions of bromination, grinard reaction, using 4,5-disubstituted henanthrene and 4,5-disubstituted 9,10-dihydrophenanthrene derivatives as starting materials. Liquid crystal monomer compounds were synthesized via sequential reactions of halogenations and coupling reaction, and the chemical structures of products were identified by 1H NMR, 13C NMR spectra.
