Ethylene bridged azobenzenes are novel, promising molecular switches that are thermodynamically more stable in the (Z) than in the (E) configuration, contrary to the linear azobenzene. However, their previous synthetic routes were often not general, and yields were poorly reproducible, and sometimes very low. Here we present a new synthetic strategy that is both versatile and reliable. Starting from
乙烯桥连的偶氮苯是新颖的,有前途的分子开关,与线性偶氮苯相反,在(Z)中比(E)构型在热力学上更稳定。但是,它们以前的合成路线通常不通用,并且产量重现性差,有时非常低。在这里,我们提出了一种既通用又可靠的合成策略。从广泛使用的2-溴苄基溴开始,可以通过三个简单步骤获得指定的分子。
