Several new non-symmetrically substituted 4,4′-diphenyl-2,2′-bithiazole derivatives were synthesized with the use of a novel synthetic methodology comprising modified Hantzsch synthesis and palladium-catalyzed Kharash cross-coupling reaction at the key steps. Mesogenic properties of the new compounds were studied by optical and calorimetric methods. The most promising for practical applications are
使用一种新的合成方法合成了几种新的非对称取代的 4,4'-二苯基-2,2'-联噻唑衍生物,包括改进的 Hantzsch 合成和钯催化的 Kharash 交叉偶联反应的关键步骤。通过光学和量热方法研究了新化合物的介晶性质。实际应用中最有希望的是容易获得的非对称 4,4'-二芳基-2,2'-联噻唑,在芳基部分的对位含有烷基和烷氧基取代基,表现出广泛的高温近晶-C阶段。
