Mechanical treatment (milling) of crystals of aromatic nitroso dimers (azodioxides) induces their dissociation and cross‐dimerizations. The mechanisms of these processes are discussed on the basis of kinetic studies and the solid‐state 15 N kinetic isotope effect, which is measured for the first time. By comparison with analogous processes in cocrystals and in melts, it appears that the reactions follow
对芳族亚硝基二聚体(偶氮二氧化物)晶体进行机械处理(研磨)会导致其解离和交叉二聚化。在动力学研究和首次测量的固态15 N动力学同位素效应的基础上讨论了这些过程的机理。与共晶和熔体中的类似过程相比,反应似乎遵循相似的机制,其中表面变形起着至关重要的作用。该系统还可以用作更广泛的固态反应机理概念研究的模型。版权所有©2013 John Wiley&Sons,Ltd.
