successful programmed synthesis of diverse designs of tetraphenylthiophene derivatives (TPTs, 16 out of 24 probable structures) and the intermediate triphenylthiophene derivatives (12 out of 20 probable structures) using optimized ‘classical’ Suzuki-Miyaura cross-coupling conditions through multiple routes starting from a single precursor, tetrabromothiophene. Our first-ever electrochemical analysis of various
我们通过多种途径,使用优化的“经典”Suzuki-Miyaura 交叉偶联条件,成功编程合成了不同设计的四苯基噻吩衍生物(TPT,24 种可能结构中的 16 种)和中间体三苯基噻吩衍生物(20 种可能结构中的 12 种)从单一前体四溴噻吩开始。我们对各种 TPT 设计的首次电化学分析强调了电子不同芳基单元的排列对 TPT 氧化电位的关键影响。这些发现提供了对 TPT 设计氧化还原趋势的见解,可能指导 TPT 中的选择性氧化 C-C 偶联以实现 π 扩展的噻吩。
