A facile synthetic route toward functionalized 3-aryl-, 3,3′-diaryl-, 3,3′,5-triaryl-4,4′-dimethoxybiphenyls (polyphenyls) 3–5 with the terphenyl, quaterphenyl, quinquephenyl, and sexiphenyl skeleton starting from biphenyl-4,4′-diol (1) in modest total yield is described. The route has been carried by the two transformations of the regioselective NBS (N-bromosuccinimide)-mediated bromination of 2 in
一条易于合成的路线,可将功能化的3-芳基-,3,3'-二芳基-,3,3',5-三芳基-4,4'-二甲氧基联苯3 – 5与三联苯,四联苯基,五联苯基和六联苯基描述了从联苯-4,4'-二醇(1)开始的骨架,其总收率不高。该路线通过两次选择性转化由区域选择性NBS(N-溴代琥珀酰亚胺)介导的MeCN在回流下的2溴化反应和所得溴化物与DME回流下的DME中的芳基硼酸6的Suzuki-Miyaura交叉偶联反应完成。
