study the effect of the substituents in the N-position of the carbazole on anionicpolymerization, 2-vinylcarbazole derivatives of 9-butyl-2-vinylcarbazole (NBu2VCz), 9-phenyl-2-vinylcarbazole (NPh2VCz), and 9-(pyridin-2-yl)-2-vinylcarbazole (NPy2VCz) were synthesized. The anionicpolymerization of NBu2VCz and NPh2VCz using s-BuLi was performed at −78 °C with a 100% yield, but the polymerization of NBu2VCz
为了研究咔唑N位上的取代基对阴离子聚合的影响,分别使用了9-丁基-2-乙烯基咔唑(N Bu2VCz),9-苯基-2-乙烯基咔唑(N Ph2VCz)和9的2-乙烯基咔唑衍生物合成了-(吡啶-2-基)-2-乙烯基咔唑(N Py2VCz)。使用s -BuLi进行N Bu2VCz和N Ph2VCz的阴离子聚合反应是在-78°C下以100%的收率进行的,但是N Bu2VCz的聚合反应显示出 比N Ph2VCz宽的分子量分布(M w / M n = 1.23)。(中号瓦特/M n = 1.11)。使用s -BuLi和DPM-K进行N Py2VCz的阴离子聚合,收率低于5%。特别地,N ph2VCz与s -BuLi /苯乙烯([ s -BuLi / St] 0 = 0.33)的活性阴离子聚合显示出较窄的M w / M n。成功实现了N Ph2VCz与苯乙烯,α-甲基苯乙烯(α-MeSt)和2-乙烯基吡啶(2VP)的嵌段共聚。所得的P

A convenient and efficient palladium-catalyzedC-Hbondactivation for the assembly of N-aryl carbazole is reported, in which two C-N bonds were formed under one set of conditions. The desired carbazoles were achieved in decent yields with a wide substrate scope by utilizing readily available 2-iodo biphenyls and aromatic amines as starting materials.
