Abstract
Rapid CuAAC cross-coupling reactions catalyzed by CuBr/PMDETA in toluene afforded complex architectures from functional polymeric cyclic blocks. Various topologies (from paddle-like to 3-arm stars) rapidly formed with high conversion at 25 °C. Remarkably, this approach overcame significant steric hindrance linking polymeric cyclic structures with high coupling efficiency.
摘要
快速的 CuAAC 交叉偶联反应在甲苯中由 CuBr/PMDETA 催化，从功能化的聚合物环状块得到复杂的结构。各种拓扑结构（从桨状到 3 臂星状）在 25°C 时迅速形成，并具有高转化率。值得注意的是，这种方法克服了连接聚合物环状结构的巨大空间位阻，具有高的偶联效率。
