Diazocines are azobenzene derived macrocyclic photoswitches with well resolved photostationary states for the ()- and ()-isomers, which improves their addressability by light. In this work, effective procedures for the stannylation and borylation of diazocines in different positions are reported. Their use in Stille cross-coupling and Suzuki cross-coupling reactions with organic bromides is demonstrated in yields of 47-94% (Stille cross-coupling) and 0-95% (Suzuki cross-coupling), respectively.
重氮辛是一种由偶氮苯衍生的大环光开关，其（）-异构体和（）-异构体具有良好分辨的光稳态，这提高了它们通过光进行寻址的能力。在这项工作中，报道了在不同位置对重氮辛进行锡基化和硼基化的有效方法。分别以47-94%（Stille交叉偶联）和0-95%（Suzuki交叉偶联）的产率证明了它们在与有机溴化物的Stille交叉偶联反应和Suzuki交叉偶联反应中的应用。
