New insights into the reaction pathways of different potassium/magnesium amide-hydride based systems are discussed. In situ SR-PXD experiments were for the first time performed in order to reveal the evolution of the phases connected with the hydrogen releasing processes. Evidence of a new K-N-H intermediate is shown and discussed with particular focus on structural modification. Based on these results, a new reaction mechanism of amide-hydride anionic exchange is proposed.
讨论了对不同基于钾/镁酰胺-氢化物体系反应途径的新见解。首次进行了原位同步辐射粉末X射线衍射（SR-PXD）实验，以揭示与氢释放过程相关的相的演变。展示并讨论了一种新的K-N-H中间体的证据，特别关注结构修饰。基于这些结果，提出了一种新的酰胺-氢化物阴离子交换反应机制。
