Suzuki–Miyaura coupling reactions of 5-chloro-1-phenyl-tetrazole with various functionalized arylboronic acids were investigated. In the presence of catalytic amounts of SPhos/Pd(OAc)2 or RuPhos/Pd(OAc)2, the reaction proceeded smoothly to afford 1,5-diaryltetrazoles in good to excellent yields.
研究了5-氯-1-苯基-四唑与各种官能化的芳基硼酸的Suzuki-Miyaura偶联反应。在催化量的SPhos / Pd(OAc)2或RuPhos / Pd(OAc)2的存在下,反应平稳进行,以良好的产率至优异的产率得到1,5-二芳基四唑。
