electrochemical actuators, were synthesized via a novel, efficient acid-catalyzed reaction of 2-acylbenzoisocyanate at room temperature. Real-time NMR analysis and the captured intermediate showed the mechanism was an unprecedented cyclization of the isocyanate with the neighboring acyl group, followed by the dimerization.
二苯并[ b,f ] [1,5]重氮电影,一类潜在的新型电化学致动器的组成部分,是通过在室温下进行新型的,有效的酸催化的2-酰基苯并异氰酸酯反应合成的。实时NMR分析和捕获的中间体表明,该机理是异氰酸酯与相邻酰基的空前环化,然后是二聚化。
